Zurich Instruments - Model MFIA -500 kHz / 5 MHz Impedance Analyzer

The front panel of the MFIA features 1 current signal input, 1 differential voltage input, 1 differential signal output, 2 auxiliary inputs that can work as reference inputs, and 4 auxiliary outputs. Both signal inputs and outputs can be operated in single-ended and differential mode for experiments that require extra noise immunity. The signal ground can be referenced to the instrument ground or to the BNC shield of the signal inputs.

The back panel offers additional BNC connectors comprising 2 trigger inputs, 2 trigger outputs, and 1 input and 1 output for 10 MHz clock synchronization. Moreover, a SCSI connector offers access to all DIO channels. The units can be operated with standard 90 - 240 V mains supply or by an external 12 V DC power supply (e.g., an external battery pack) to break up ground loops.

Temperature changes of the instrument can severely limit start-up speed and measurement repeatability. The MFIA performs exceptionally well in both aspects, as shown by the start-up drift graph above and by the reactance chart at the bottom of the page. You can start the first measurements after 25 s from turning on the instrument.

Voltage measurements and current measurements are both supported by the MFIA. The analog front end features variable input impedance as well as AC/DC coupling selection, and the high-frequency analog to digital sampling provides a large oversampling factor. This ensures superior lock-in performance and high signal fidelity for the Scope.
