Note

The PAUSE feature can be useful when measuring the average value from certain rotating radars. The effective measurement technique requires you to pause during the period of time when you are not in the beam of the radar. Continue this technique for two or more revolutions (depending on the RPM) to obtain a realistic average value of the field in the beam at your loca- tion. For details on this measurement technique, see Radar Measurements in the Applications Booklet.

13.To temporarily suspend the time average mode (once the current measurement interval has been completed or stopped) and make real time measurements, press F2 (CLR). To make another time-averaged measurement under the same conditions, press F1 (START) again.

14.To end time averaging altogether and return to the standard measurement screen (once the current measurement interval has been completed or stopped), press F4 (QUIT). To initiate time averaging again at a later point, use the menu system to select TIME AVG from the First Menu Screen.

2.You may continue to pause and start the averaging as many times as needed. The time interval determined by the standard and the frequency applies only to the measurement time (excludes time when "PAUSED").

3.To end time averaging while *PAUSED*, press F4 (STOP).
