Description
This softkey lets you compensate for system, cable, and waveguide
variations due to changes in frequency,by linearly increasing or
decreasing p ower output as the frequency increases. RF slop e values
may range from
0
2.50 to +2.50 dB p er GHz. The power at the
beginning of the sweep equals the currentpower level. An asterisk
next to the key lab el indicates that this feature is active.

Analyzer:
SL1 function on, SL0 function o. Note that b ecause SL
functions in the fundamental units of dB/Hz, you program the SL
co de SLmdt, where m is 1 (on) or 0 (o ); d is the n
umerical value
in dB/Hz, and t is either \DB" or the ASCII LF terminator. F
or
example, for a slop e of 1.5 dB/GHz use this pro cedure:
1. 1.5 dB/GHz = 1.5 dB/1,000,000,000 Hz
2. 1.5 dB/1E9 Hz = 1.5E-9 dB/Hz
3. The programming co de is \SL11.5E-9 DB"
