HP-IB Command Guidelines

Guidelines for Operation

Reading back the measurement, instrument function, or data

function state

Use the query form of the command, STATe?, to determine the current

state of a measurement, instrument function or data function. If a

measurement, instrument function, or data function is queried, the

returned value will be either a “1” (ON) or a “0” (OFF).

For example, the following BASIC language statements illustrate the

use of the STATe? command to determine the current state of the TX

Power measurement:

Example 3-32 Example

!Query the state of the TX Power measurement

OUTPUT 714;"MEAS:RFR:POW:STAT?"

ENTER 714;State_on_off

IF State_on_off = 1 THEN DISP "TX Power Measurement is ON"

IF State_on_off = 0 THEN DISP "TX Power Measurement is OFF

STATe Command Guidelines
