Low Range
Amplitude –7.8 mA to +7.8 mA
Bin size
Both ranges are filled when the histogram runs. Measurement magnitudes that fall within the low
range are automatically placed in the low-range histogram. The values for both histogram ranges can
be queried as follows:
SENS:HIST:CURR:BIN:RANG? (@1)
This query returns the amplitudes of the high and low range. These amplitude limits are subsequently
used by other SCPI commands when returning the histogram counts for the specified range.
Programming a current histogram measurement consists of:
Selecting the histogram function and range.
l
Specifying the trigger source.
l
Initiating and triggering the histogram.
l
Retrieving the histogram measurement.
l
Querying the histogram bin and offset to calculate amperes.
l
Histograms cannot be programmed from the front panel and cannot run simultaneously with any other
measurement. When a histogram measurement is initiated on an output channel, the front panel
changes to Meter view. Any channel that is performing a histogram measurement displays a message
to this effect. Switching to Scope or Data Logger view will terminate the histogram measurement.
Select the Histogram Function and Range
The following command selects a measurement function. To enable current histogram measurements
on channel 1:
SENS:HIST:FUNC:CURR ON,(@1)
Each output channel uses its own current measurement range, which includes autoranging. To select
the 3 A current range on channel 1:
SENS:HIST:CURR:RANG 3,(@1)
Seamless Measurements - For Keysight Models N6781A, N6782A, N6785A, and N6786A, you can
select seamless current autoranging, which results in a wide dynamic range with no data lost across
ranges. Seamless ranging does not include the 10 μA range, which must be selected manually. To
enable seamless current autoranging on channel 1:
SENS:HIST:CURR:RANG:AUTO ON,(@1)
