4 Key Reference
Ext Amp Gain Softkey adds a positive or negative preamplifier gain value,
which is subtracted from the displayed signal. (Use negative
values for gain and positive values for loss.) The function is
similar to the Ref Lvl Offset function, however with the Ext Amp
Gain function, the attenuation may be changed depending on
the preamplifier gain entered. A preamplifier gain offset is
used for measurements that require an external preamplifier
or long cables. The offset is subtracted from the amplitude
readout so that the displayed signal level represents the
signal level at the input of the preamplifier. The preamplifier
gain offset is displayed at the top of the screen and is
removed by entering zero. The preamplifier gain offset can
only be entered using the numeric keypad. The preamplifier
gain value is not affected by an instrument preset or a
power cycle.
