MF-MD Multi-Demodulator

The MF-MD Multi-Demodulator option broadens the capabilities of the MFLI and the MFIA by increasing the number of demodulators to 4 and the number of oscillators to 4. It also provides an additional external reference PLL (for a total of 2), and enables simultaneous DC offset and AC signal measurement.

Upgrading the MFLI Lock-in Amplifier with this option enables simultaneous measurements of the current input and of the voltage inputs, as required for a number of applications. Moreover, data for up to 4 arbitrary frequencies – including higher harmonics – can be extracted from a signal at the same time. It is also possible to set each demodulator's input and filter settings independently.

When combined with the MF-IA option for the MFLI or installed on the MFIA Impedance Analyzer, the MF-MD option adds a second impedance measurement unit to the instrument and allows users to probe the device under test at 2 frequencies simultaneously. This feature can thus help to simplify the setup for experiments involving multiple frequencies and speed up measurements by up to a factor of 2.

The table below provides an overview of the main features associated with the MF-MD Multi-Demodulator option.
