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:
Front Panel: SCPI Command:
Select the Meter key. To measure average voltage or current:
MEAS:VOLT?(@1)
MEAS:CURR?(@1)
Measurement Ranges
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.
Front Panel: SCPI Command:
Select Measure\Range.
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:
3.06 A range To select, program values > 0.1 A and ≤ 3.06 A.
0.10 A range
To select, program values > 200
µ
A and ≤ 0.1 A.
200 μA range (option 2UA)
To select, program values ≤ 200 µA.
Seamless Measurements
Seamless voltage and current measurement autoranging is available
on Agilent Models N6781A and N6782A. 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.
Front Panel: SCPI Command:
Not Available To enable seamless voltage or current
autoranging on channel 1:
SENS:VOLT:RANG:AUTO ON, (@1)
SENS:CURR:RANG:AUTO ON, (@1)
