65 Chapter 9 Time-Averaged Measurements
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.
To temporarily pause during a time averaged
measurement...
1. To temporarily suspend time averaging, press
F3 (PAUSE). The word *PAUSED* will appear on the
fourth line of the display. To resume time averaging
and complete the measurement, press F1 (START).
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").

The PAUSE feature
can be useful when
measuring the aver-
age value from cer-
tain rotating radars.
The effective mea-
surement technique
requires you to
pause during the pe-
riod of time when
you are not in the
beam of the radar.
Continue this tech-
nique for two or
more revolutions
(depending on the
RPM) to obtain a re-
alistic average value
of the field in the
beam at your loca-
tion. For details on
this measurement
technique, see Ra-
dar Measurements
in the Applications
Booklet.
