Digitize voltage measure settings
The following options are available on the Measure Settings menu when the function is set to digitize
voltage.
Setting Description/reference
Range
Determines the full-scale input for the measurement; also affects
the accuracy of the measurements and the maximum signal that
can be measured. Refer to Ranges (on page 3-3).
Display Digits
Sets the number of digits that are displayed for front-panel
readings. It does not affect accuracy or speed. Refer to Setting the
number of displayed digits (on page 2-55).
Signal Coupling
Determines if AC or DC signal coupling is used. When DC is
selected, the instrument measures AC and DC components of the
signal. When AC is selected, the instrument only measures the AC
components of the signal.
Input Impedance
Sets impedance to Auto or 10 MΩ; see DC voltage input
impedance (on page 2-98).
Aperture
Sets the measurement aperture time.
Sample Rate
Sets the number of readings per second.
Count
Sets the number of aperture readings that are processed when a
measurement is requested.
Unit
Sets the units of measurement that are displayed on the front panel
of the instrument and stored in the reading buffer.
AC Coupling Filter
Available when Signal Coupling is set to AC: Sets the instrument
settling time. Set to Slow to allow more settling time or Fast to
allow less settling time.
AC Coupling
Frequency
Available when Signal Coupling is set to AC: Sets an amplitude
that compensates for signal loss across the coupling capacitor.
Decibel Reference
Sets decibel reference point; this setting is only available when Unit
is set to Decibel. Refer to Show voltage readings in decibels (on
page 2-98).
Digitize current measure settings
The following options are available on the Measure Settings menu when the function is set to digitize
current.
Setting Description/reference
Range
Determines the full-scale input for the measurement; also affects
the accuracy of the measurements and the maximum signal that
can be measured. Refer to Ranges (on page 3-3).
Display Digits
Sets the number of digits that are displayed for front-panel
readings. It does not affect accuracy or speed. Refer to Setting the
number of displayed digits (on page 2-55).
Aperture
Sets the measurement data acquisition time window time.
Sample Rate
Sets the number of aperture readings per second.
Count
Sets the number of aperture readings that are processed when a
measurement is requested.
