Mô tả Sản phẩm

With a built-in Rubidium atomic resonance-controlled frequency reference, the PM 6685R is the most accurate frequency counter on the market and it has the additional benefit of full portability.

High stability, high accuracy and short warm-up time make this instrument ideal for high-accuracy calibration procedures outside the calibration laboratory environment, such as in base station transmitters of large telecommunications networks like GSM.
The short warm-up time makes that the PM 6685R is ready for use quickly, for example after transport or change of location inside a building.
High-resolution digital frequency counting
Frequency calibration to relative accuracies of better than 1 part in 108 has traditionally required complicated setups, or have been time-consuming to perform, with frequency counters that needed long measuring times to achieve the required resolution.
With a virtual clock frequency of 4 GHz, Fluke's PM 6685R offers an unmatched resolution of 2.5 x 10-10 per second, giving 10 reliable read-out digits in only one or a few seconds. This makes high-accuracy calibration measurements possible, with the convenience of requiring only a digital counter.
The wide choice of input options allows digital calibration measurements at up to 8 GHz, without the complexity of needing to use synthesizers, mixers and filters to provide the required resolution down to the last digits.

Additionally, digital counting techniques allow a numerical offset or nulling of the display value to make it easy to read changing or arbitrary frequency values with many different digits.
Guaranteed high stability for field operation
The built-in Rubidium reference solves the practical problems of ensuring very high stability under severe field conditions.
The atomic resonance principle of rubidium standards is intrinsically 100 times more stable than an electromechanical crystal resonator; a fact that contributes to making the PM 6685R the most accurate counter/calibrator available for field use.
Also, the atomic reference does not suffer from mechanical, thermal, vibrational and line voltage influences in the way that a crystal oscillator would. When carrying a crystal-based counter, for example, just one small bump against a step can cause more frequency change than several months of aging under controlled calibration laboratory conditions.
This stronger resistance to environmental stress on the reference permits longer calibration intervals in many practical situations, making the PM 6685R more convenient for field personnel and reducing the cost of ownership. In fact, using the PM 6685R at a field site may even reduce the need to send other elements of a field lab out for their own respective calibration.
Rubidium references should therefore be considered for all meaurements or calibrations in the field where accuracies better than a few parts in 108 are required, or where frequent calibration of the counter is not possible.

CTC100 Cryogenic Temperature Controller

Introducing the new CTC100 Cryogenic Temperature Controller — a high performance instrument that can monitor and control temperatures with millikelvin resolution.

The CTC100 Cryogenic Temperature Controller is configured to suit a wide range of research and industrial applications. The system consists of four sensor inputs, two powered and four analog voltage outputs, and up to six feedback control loops. Four general purpose analog and eight digital I/Os are available, along with autotuning functions for setting PID parameters automatically.

Sensor Inputs

The CTC100 offers four temperature inputs that can read RTDs, thermistors, and diodes. Each temperature input channel has its own 24-bit ADC with eleven input ranges, and is equipped with its own independent excitation current source.

Channel setup menu

Standard calibration curves for a variety of sensors are included, and custom calibration curves of up to 200 points each can be entered. Each sensor input has high and low level or rate-of-change alarms. Sensor inputs can be lowpass-filtered to reduce noise, and/or differenced with another channel.

Powered and Analog Voltage Outputs

The CTC100 has two heater outputs that can each deliver up to 100 W of power to a 25 Ω heater. In addition, four analog voltage I/O channels can be used to drive heaters with the help of an external amplifier.

Select menu

PID Feedback Control

With up to six feedback control loops available, the CTC100 can provide precise temperature control of each of its heater outputs by continually adjusting the heater power. Any of the CTC100’s channels can be selected as the input for each feedback loop. Feedback time constants can be adjusted between 200 ms and 10 hrs.

Up to ten sets of PID parameters can be stored for each channel. Setpoints can be ramped at a fixed rate (or with a user program), set from an analog input.

Numeric display

Analog and Digital I/Os

The CTC100 comes with four general-purpose ±10 V voltage I/O channels read by a 24-bit ADC. It also has eight digital I/O channels that can interact with user programs.

Four 5 A relays can be used for process control. Three virtual channels, not connected to any physical input, allow calculated values (such as the difference between two channels, or a value calculated by a user program) to be displayed, graphed, and logged.

Graphical display

Numeric and Graphical Display

The CTC100’s color LCD display can show any combination of temperature measurements and heater outputs on graphs or numeric displays. Up to eight channels can be plotted either on a single graph with a common Y axis, or on separate graphs with independent Y axes. Touchscreen operation makes the instrument versatile and easy to use.

Data Logging

Up to 4096 readings per channel can be logged to the CTC100’s internal memory. For longer-term storage, data can be logged to standard USB memory sticks or hard drives.

Data logged to USB devices can be transferred to a computer by plugging the USB device into a PC. Windows applications are included to graph CTC100 log files and to convert them to various ASCII text formats.

Computer Communications

Each of the CTC100’s front-panel controls has a corresponding text command that can be sent over USB, Ethernet, and either RS-232 or an optional GPIB interface.

When the USB interface is used, the CTC100 appears on the computer as a standard COM port and can be controlled by any software that is compatible with an RS-232 port.

User Programs

User programs (macros), consisting of one or more remote commands, can be uploaded to the CTC100. This is done by either sending them through one of the communications ports or by saving them as text files on a USB memory device and then plugging the device into the CTC100. Program macros can also be entered and edited from the front panel.

Model 7270 - Overview

The model 7270 sets a new standard for general-purpose DSP lock-in amplifiers. We've taken advantage of the developments in technology since the first DSP lock-in amplifiers were introduced in the early 1990’s to update the core design, but made sure that we’ve included all the best features of our model 7265 and 7280 instruments. What’s more, the new architecture has allowed us to offer even better specifications in an instrument that is physically much more compact than older designs. The result is a lock-in amplifier of outstanding performance that is easy to use and suitable for all measurements over a frequency range extending from 1 mHz to 250 kHz.

Versatility
In common with other models in our range, the 7270 offers much more than just dual phase lock-in detection at the reference frequency of an applied signal. We’ve included features unique to SIGNAL RECOVERY instruments such as dual reference and dual harmonic detection, which allow signals at two different frequencies to be measured simultaneously. The spectral display mode shows the power spectral density of the input signal, making it easy to avoid interfering signals when selecting a reference frequency. It is now even possible to perform tandem demodulation. In this mode an amplitude-modulated signal at a (high) “carrier” frequency is first demodulated at that frequency. The resulting in-phase output, at short time constant settings, is a signal at the modulating frequency which is then passed forward for detection by a second set of demodulators running at the same modulating frequency. Such detection techniques, which can be used in pump-probe measurements, have until now required two separate instruments with an analog connection between them.

Fast Data Processing
The main ADC sampling rate and the rate at which the analog signal outputs are updated is 1 MSa/s, giving excellent performance when used at short output filter time constant settings, such as in scanned probe measurements. But we’ve also increased the maximum rate at which data can be stored to the internal curve buffer to 1 μs per point, allowing for the first time direct capture of instrument outputs when using these short time constants. The buffer length has also been increased to 100,000 sets of points, giving recording times of 100 ms at the fastest sampling rates. What’s more, in the fast capture mode the length does not need to be divided by the number of outputs being stored, making it possible, for example, to store the full 100,000 points of X, Y and auxiliary ADC1 values at the same time.

Remote Control
The built-in RS232, USB and Ethernet connections allow full operation from a controlling computer. We offer a comprehensive software package, Acquire, that can operate the instrument via any of these interfaces and makes it easy to set up and run complex experiments, such as frequency response measurements, as well as allowing remote control of every instrument function. Users who wish to do their own programming can use our ActiveX control and toolkit (SRInstComms), or free LabVIEW driver, to simplify the task.

See what you’ve been missing...
In summary, if you’re looking for a general purpose lock-in to work in the range 1 mHz to 250 kHz then you need look no further - you’ve found it in the SIGNAL RECOVERY model 7270.

1 mHz to 250 kHz operating frequency range
1.0 MHz main ADC sampling rate
10 µs to 100 ks output filter time constants
Dual Reference, Dual Harmonic and Virtual Reference operating Modes
Internal data buffer for recording instrument outputs at rates down to 1 µs per point
USB, RS232, and Ethernet computer interfaces

The PGW balances meet the standards of reliability and quality that Adam’s customers expect. The metal housing is much more rugged than plastic cases and has been designed to divert spills away. The large, stainless steel pan can be removed for easy cleaning or storage.

PGW laboratory balances offer valuable features like track weights of tared objects and their contents. Simply using the tare key, you can automatically track every component of the weighing process, whether you need to know the value of the tared container, the goods it contains, or the total of both together. The PGW’s display can show both the total gross weight and the net weight at the same time when needed.

Quality control checks made simple with the Adam PGW753i. Filling and checking the weight of objects with this balance makes it easy to meet your quality control expectations. Set your own limits and the display will indicate when the weight is too low, too high or on the mark and a selectable warning indicates when you are on target. The software’s true flexibility lets you select one or two target points. Use the capacity tracker to give you a visual perspective of your check weighing.

Weighing and customized units. Up to 17 weighing units are included as standard, offering you the flexibility needed for every laboratory application. One custom unit allows you to perform independent custom calculations. For example; using the PGW to work out a cost per weight reading, or a weight per square meter, gives you added flexibility.

This precision lab balance comes with color coded keys and large LCD display for easy operation. Brilliant backlit display with 1” high digits and graphic capacity tracker. Two adjustable feet and leveling bubble insures proper and accurate readings. Weigh below hook for weighing hot or magnetic materials plus density and specific gravity measurements (under hook is an optional accessories found in the optional accessories section by scrolling further down).
