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 time interval is 20.48 microseconds. The output window
function is Rectangular.
Use the following commands to make a simple measurement:
Select the Meter key.
To measure average voltage or current:
MEAS:VOLT?(@1)
Some models have multiple voltage and current measurement ranges.
(Refer to Chapter 1, “Model Differences”). Selecting a lower
measurement range provides greater measurement accuracy, provided
the measurement does not exceed the range.
Select
.
Select the lower measurement
range from the voltage or
current dropdown menu. Then
press Select.
To set the 5 V measurement range:
SENS:VOLT:RANG 5, (@1)
To set the 1 A measurement range:
SENS:CURR:RANG 1, (@1)
The maximum measurable current is the maximum rating of the range. If
the measurement exceeds the range, an “Overload” error will occur.
Examples of programming measurement ranges are:
To select, program values > 0.1 A and ≤ 3.06 A.
To select, program values > 200 µA and ≤ 0.1 A.
200 μA range (option 2UA)
To select, program values ≤ 200 µA.
Seamless voltage and current measurement autoranging is available on
Keysight Models N6781A, N6782A, N6785A, and N6786A. This enables a
wide dynamic measurement range with no data lost across ranges.
Autoranging does not include the 10 μA range, which must be selected
manually.
Select
.
Select Auto from the voltage
or current dropdown menu.
Then press Select.
To enable seamless voltage or current
autoranging on channel 1:
SENS:VOLT:RANG:AUTO ON, (@1)
SENS:CURR:RANG:AUTO ON, (@1)
