Boonton 9240 Series RF Voltmeter
*OPT?
Description: Return the status of Channel 1 and Channel 2 followed by a list of installed options.
Syntax: *OPT?
Returns: <f1, f2, f3, f4, opt1, opt2, …> : f1 – Chan 1 installed?, f2 – Chan1 sensor present?, f3 – Chan 2
installed?, f4 – Chan 2 sensor present?, opt1, opt2, etc. (option list may be empty).
*RST
Description: Set the instrument to a known “default” configuration. Set measurements to STOP. Set the sensor
temperature offset flag to FALSE, set the SCPI file over-write permission to FALSE, turn the
internal Calibrator output OFF and clear the error queues. System communication parameters are
not changed. Instrument measurement functions are set their default values (See Table 3-3,
Initialized Parameters).
Syntax: *RST
Argument: None
*SRE
Description: Set or return the mask value in the Service Request Enable Register. This value is used to enable
particular bits for generating a service request (SRQ) over the GPIB when certain conditions exist
in the Status Byte register. When a mask bit in the SRE Register is set, and the corresponding
STB register bit goes true, an SRQ will be generated. No SRQ can be generated for that condition
if the mask bit is clear. The bits in the Status Byte register are generally summary bits, which are
the logical OR of the enabled bits from other registers. See the *STB command for bit
assignments.
Syntax: *SRE <numeric value>
Argument: <numeric value> = 0 to 255
