Power Monitor (External Detector) (Option 5)
Selecting
Power Monitor (External Detector)
from the mode menu causes the soft keys, de-
scribed below, to be displayed and the corresponding values shown in the message area.
q
Units
— Toggles between dBm and Watts.
q
Rel
— Turns relative mode OFF, if currently ON. If relative mode is cur-
rently OFF, turns it ON and causes the power level to be measured and saved
as the base level. Subsequent measurements are then displayed relative to this
saved value. With units of dBm, relative mode displays dBr; with units of
Watts, relative mode displays % (percent).
q
Offset dB
— Turns Offset OFF, if currently ON. If Offset is currently OFF,
turns it ON and opens the Offset parameter for data entry (0-60). Press
ENTER
when data entry is complete.
Offset is the attenuation (in dB) inserted in the line between the DUT and the
RF detector. The attenuation is added to the measured input level prior to dis-
play.
q
Zero
— Turns Zero OFF, if currently ON. If Zero is currently OFF, this soft
key turns it ON and initiates collection of a series of power level samples,
which are averaged and saved. This saved value is then subtracted from sub-
sequent measurements prior to display.
q
Measure Offset
— Measures the exact loss of phase stable cables and
attenuators attached to the unit. The Anritsu Power Meter Offset Cal Kit, part
number 65701 which includes a jumper cable and 10 dB attenuator, is recom-
mended for this offset calibration. Measure Offset is recommended when per-
forming measurements requiring high accuracy.
