Digitizing Measurements

162
The digitizing measurements discussed in this section allow you to
perform most but not all of the scope measurement function available
on the front panel. One example of functionality not available over
the remote interface is the ability to program markers and make
calculated measurements between markers.
With the digitizing measurement functions you can:
Specify a measurement function and range.

Adjust the measurement sample rate.

Adjust the measurement to capture pre-trigger data.

Select a measurement window that can attenuate AC noise.

Select the measurement trigger source.

Initiate the trigger system and generate a trigger.

Retrieve the digitized measurements.

When a measurement is in progress over the remote interface, the front panel
NOTE
display may indicate "-- -- -- -- --". Front panel measurements resume when the
remote measurement completes.
Select the Measurement Function and Range
The following commands select a measurement function. To enable
voltage measurements on channels 1 through 4:
SENS:FUNC:VOLT ON,(@1:4)
To enable current measurements on channels 1 through 4:
SENS:FUNC:CURR ON,(@1:4)
If a model has simultaneous measurements (see chapter 1, "Power
Module Features"), then BOTH voltage and current measurements
can be enabled.
Some models also have multiple measurement ranges. Selecting a
lower measurement range provides greater measurement accuracy,
provided that the measurement does not exceed the range. To select
the low voltage range on channel 1:
SENS:VOLT:RANG 5,(@1)
To select the 1 A current range on channel 1:
SENS:CURR:RANG 1,(@1)
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.
