Description
Allows you to select an external pad, an external preampliEer, and measure
total power at the input to the analyzer. An external 50
D
to 75
62
pad is used
for analyzers with 50
Q
input impedances. The EXT PAD YES
NO
function
compensates for amplitude loss caused by an external pad.
An external preamplifier (or the internal preamplifier in HP 8591C analyzer)
is used for the carrier-to-noise test.
The external pad and preampliEer settings are stored in non-volatile analyzer
memory. This means that the analyzer retains the selection, even when
power is turned off, until a new selection is made.
The
TDTL
PWR
(8
INPUT measures the total input power and displays the
result on the screen.
