Is it possible to supply a DC voltage to a device under test with the E5091A?
(SUPPORTED MODELS IN BOLD: E5071C E5072A E5070B/71B E5070A/71A E5061A/62A E5061B E5063A E5091A E5092A)
Yes. The E5091A multiport test set has the capability to provide DC voltage to a device under test (DUT). Please refer to the details below.
In Figure 1 below, assume that the goal is to provide a DC voltage to the Vc pin of the DUT.
The Keysight E5091A multiport test set provides 8 control lines (Line 1 - Line 8) at the front panel that can output a DC voltage (see Figure 2).
These 8 output lines can be set to "High" or "Low" and are controlled via the ENA. The DC level of the "High" or "Low" is determined by the voltage supplied to pins 13 and 14 respectively. There are 2 methods to supply voltage to pins 13 and 14, internal power supply on E5091A or external power supply.
Method 1 - Use of internal power supply on E5091A
As shown in Figure 3 Pin 13 (Positive Input) and pin 14 (Negative Input) are connected to pin 12 (+2V - +5V) and pin 15 (GND) respectively. With this connection, control lines set to "High" will output a voltage in the range of +2V to +5V. This "High" voltage can be adjusted by rotating the voltage adjustment trimmer at the front panel. Control lines set to "Low" will output 0V (ground).
Method 2 - Use of an external power supply
Pin 13 and pin 14 are connected to an external DC power supply, as shown in Figure 4. With this connection control lines set to "High" will output a voltage ranging from 0V to +5V (depending upon the output of the power supply). Control lines set to "Low" will output a voltage ranging from -5V to 0V (depending upon the output of the power supply).
