This
softkey
lets you compensate for system, cable, and waveguide
variations due to changes in frequency, by linearly increasing or
decreasing power output as the frequency increases. RF slope values
may range from -2.50 to j-2.50 dB per GHz. The power at the
beginning of the sweep equals the current power level. An asterisk
next to the key label indicates that this feature is active.

function on, SLO function off. Note that because SL
functions in the fundamental units of
dB/Hz,
you program the SL
code
SLmdt,
where m is 1 (on) or 0 (off); d is the numerical value
in
dB/Hz,
and t is either “DB” or the ASCII LF terminator. For
example, for a slope of 1.5 dB/GHz use this procedure:
1. 1.5 dB/GHz = 1.5 dB/1,000,000,000 Hz
2. 1.5
dB/lES
Hz = 1.5E-9

3. The programming code is “SL11.5E-9 DB”
