Figure 51: HVM1212A High-Voltage Matrix
In 3000 V high-voltage, low-current systems, the HVM1212A connects pass-through signals to the
707B low-current matrix through protection modules to one of the 7531 matrix cards. This allows you
to do high-voltage, low-voltage, low-current, and capacitance tests in a single probe touch-down.
The following figure shows the connections on the rear panel of the HVM1212A.

Sourcing and measuring
The following instruments provide S540 source-measure capabilities.
Model 2657A High-Power System SourceMeter Instrument
The Model 2657A is a high-voltage, high-power, low-current source measure unit (SMU) instrument.
You can have up to two 2657A SMUs in the S540.
