Parameters
Query
Description
<n> = 3 to 300e3 Specify bandwidth (in Hz)
BANDwidth? Query selected bandwidth
The Model 2016 uses three bandwidth settings for ACI and ACV
measurements; 3 (3Hz-300kHz), 30 (30Hz-300kHz) and 300 (300Hz-
300kHz). To achieve best accuracy, you should use the bandwidth setting that
best reflects the frequency of the input signal. For example, if the input signal
is 40Hz, then a bandwidth setting of 30 should be used.
These commands are used to select bandwidth for the ACI and ACV
functions. To set the bandwidth, simply specify (approximately) the
frequency of the input signal. The Model 2016 will select the optimum
bandwidth setting.
NOTE For bandwidth setting of 3 and 30, the normal A/D reading con-
version method is not used. Thus, the NPLC setting is only valid
for bandwidth setting of 300.
Use these commands to set the maximum range input (signal level) for
frequency and period measurements.
<n> = 0 to 1010 Specify signal level in volts (voltage threshold)
:RANGe? Query maximum signal level
These commands are used to specify the expected input level. The instrument
will then select the most sensitive current or voltage threshold range.
