Boonton 9240 Series RF Voltmeter
5.5.3 CALibration Subsystem
The CALibration group of commands is used to control automatic zero offset to the RF Voltage probe and the channel to
which it is connected. Zero offset adjustment can be performed at any time if no RF signal is applied to the probe.
The numeric suffix of the CALibration commands refers to a measurement channel, that is CALibration1 and CALibration2
refer to CH1 and CH2 input channels, respectively.
Note that CALibration2 commands will generate an error if used with a single channel Model 9241. Also note that although
CALibration commands do not accept any arguments, all have a query form, which returns a status code upon completion of
the zero process. This allows the user to determine when the process has completed, and whether or not it was successful.
CALibration:ZERO
Description: Performs a zero offset null adjustment. The sensor does not need to be connected to any calibrator
for zeroing – the procedure is often performed in-system. However, this command will turn off
the internal calibrator prior to zeroing to avoid the need to perform this step explicitly.
Syntax: CALibration[1|2]:ZERO[?]
Returns: 0 if successful, 1 otherwise (using query form only)
