Command Reference
Commands which have no parallel in local operation are described fully in this section, and are indicated by the
<hP-18=>logo in the header. Commands which operate instrument functions available from the front panel are
described only briefly here, because full functional descriptions are given in the section destibing local operation.
Averaging Value <-HPI8=> " AVERage:COUNt <nrf>
When making measurements the Vector Voltmeter accumulates a number of internal readings and averages them
to produce a result which is fed to the display and/or HP-IB. The averaging value can be changed only via HP-IB.
The default is 2> measurements per reading. Higher values may reduce measurement variation , especially with
noisy signals, at the cost of a lower measurement rate. Lower values increase the measurement rate and may -
increase measurement variation.
Range 0 to 10. Default 5. The number of internal readings made is two, raised to the power of
AVERage:COUNt.
,
The query option returns the current setting.
Calibration
cat?
Performs an internal device calibration. A value of 1 will be returned if the calibration fails. A value of 0 indicates
successful calibration.
Capability <=nP18=>
CAPabi lity?
Returns the instrument's HP-IB capability string as follows:
' SH1, AH1, T6, TEO, L4, LEO, sR1, RL1, PPO, DC1, DT1, CO, E2
Clear Status <=HP18=>
*cLs
Clears the contents of the status register and associated status data structures. This command should be used as part
of remote instrument preset.
Configure Measurement
= SENSE <meas>
This command is used to configure the measurement that the Vector Voltmeter will make, and the results it will
return in response to a measurement query. Default is AVOLtage.
Options for <meas> are listed in the Measure section.
