Chart Output (Analog Output) - Keysight Technologies 34420A Service Manual

Chart Output (Analog Output)

You can use the Chart Output (Analog Output) connector on the rear panel to run
a strip chart recorder or similar instrument. The connector provides an output
voltage proportional to the measured voltage.
– Enable the chart output under the 5: CHART OUT command in the SYStem
– The output can range from –3.00 V to +3.00 V.
– When chart output is disabled (Off), the output is set to 0 V.
– The output impedance is 1 kW.
– The output voltage is related to the input signal as follows:
– The chart output state (including the span and null values) is stored in
– span cannot have a negative value.
– The chart output has a voltage "rollover" to prevent the loss of data, see the
Keysight 34420A Service Guide
menu.
Set the chart span under the 6: CHART SPAN command in the SYStem menu.
Set the chart offset under the 7: CHART NULL command in the SYStem menu.
You can also press
Shift Null
based upon the displayed reading. This action places a null value in the Chart
Offset register. Pressing
7: CHART NULL command where you can manually edit the null value.
