Programming a Power versus Time Measurement

This section provides an example of how to make the power versus time (PvT) measurement via GPIB.
The following procedure assumes that an active link is established between the test set and the mobile station.
See "Establishing an Active Link with the Mobile Station" on page
1. Configure PvT measurement parameters using the SETup subsystem.
2. Start the PvT measurement using the INITiate subsystem.
3. Use the INITiate:DONE? command to find out if the PvT measurement results are available.
4. Use the FETCh? command to obtain PvT measurement results.

Returned values

The measurements returned by this program are:
• Integrity returns the measurement
measurement with no errors).
• Pvt_mask returns the mask pass/fail indicator. When the multi-measurement count is greater than 1, the
PvT mask pass/fail result will return Fail (1) if any single measurement fails.
• Pvt_power returns the PvT carrier power in dBm.
• Max_offset returns the maximum offset level in dB, relative to the PvT carrier power.
