Waiting for the End of Measurement
Using the status register
The E4980A/AL's status can be detected through the status registers. This
section explains how to use the status registers to detect the end of
measurement. For a complete description of the status report mechanism,
including the specifications of each bit, see
The measurement status is reported by the operation status event register. An
SRQ (service request) is convenient for detecting the end of measurement. It
uses the information reported by this register.
To detect the end of measurement via an SRQ, use one of the following
commands:
•
•
Follow these steps to use an SRQ.
Step 1. Configure the E4980A/AL so that it generates an SRQ when the operation
status event register's bit (a bit that is set to 1 during measurement) is
changed from 1 to 0.
Step 2. Trigger the instrument to start a measurement cycle.
Step 3. When an SRQ is generated, the program interrupts the measurement cycle.
When the sweep averaging function is on, the E4980A/AL generates an
SRQ when it has finished taking a number of measurements that is equal
to the sweep averaging number.
