The Model 7210 Multichannel Lock-in Amplifier is yet another example of the innovation and product development provided by Signal Recovery. This unique instrument is the first multichannel lock-in amplifier of its kind. The design concept of the Model 7210 revolves around the idea of a single excitation signal combined with a multitude of detectors. So, the Model 7210 represents an economical solution compared to using a multitude of expensive amplifiers to work with each detector. The main features & specification points are:
- Each unit can be configured with 4, 8, 12, 16, 20, 24, 28, or 32 input channels
- Up to sixteen units can be chain linked together, giving up to 512 input channels
- Operates with an external reference only
- Software controlled, without a front panel
- Measured outputs are recorded digitally
- Currently offer one type of signal input card:
- Model 7210/99 option, which is a Voltage Input card
- Operates at frequencies between: 20 Hz & 50.5 kHz
- Sensitivity range of 100 uV to 1 V
- Two choices of software solution:
- SR7210Comms, which is an ActiveX software development toolkit
- MULTILCOK software for a complete data acquisition solution (which includes SR7210Comms)
Request for Quotation
- 20 Hz to 50.5 kHz operating frequency range
- Voltage mode inputs with 0.1 mV to 1 V sensitivity range
- All channels are calibrated to each other with synchronized data acquisition
- Independent control of each input channel
- Tandem demodulation operating mode for AM and FM input signals
- RS232 and GPIB computer interfaces
