Generating Trigger Out Signals
Each output channel can generate trigger signals that can be used by
other output channels, or routed to a pin on the digital port that has
been configured as a trigger output (TOUT). Use the following
commands to program transient trigger signals that are generated
when an output Step occurs:
Front Panel:
SCPI Command:
Use the Channel key to select the
channel that is the trigger source.
Select
Transient\Step
.
Check Enable Trigger Output. Then
press Select.
To program channel 3’s step function
to generate a trigger signal, use
STEP:TOUT ON,(@3)
Making Measurements
Each output channel has its own measurement capability. The output
voltage and current is measured by acquiring a number of samples at
the selected time interval, applying a window function to the
samples, and
averaging
the samples.
The power-on and *RST time interval and number of samples settings
yield a measurement time of 21 milliseconds per reading (1024 data
points at 20.48
µ
s intervals). The windowing function is Rectangular.
Use the following commands to make a measurement:
Front Panel:
SCPI Command:
Select the Meter key.
To measure the average output
voltage or current, use:
MEAS:VOLT?(@1:4)
MEAS:CURR?(@1:4)
Simultaneous Voltage and Current Measurements
Some models have simultaneous voltage and current measurement
capability. Refer to Chapter 1, “Model Differences” for model-specific
information.
In this case BOTH voltage and current are acquired on any
measurement, regardless of the parameter that is being measured. To
return both values of a simultaneous measurement:
Front Panel:
SCPI Command:
Not available.
First, measure either the output
voltage (or current):
MEAS:VOLT?(@1:4)
Then Fetch the other parameter:
FETC:CURR?(@1:4)
