HP 8590 L-Series User Manual

provides a convenient starting point for making most measurements. Pressing
@Z%?i] displays softkeys used for accessing the operating modes available
for your spectrum analyzer. See Table 7-10 and Table 7-11 for the conditions
established by pressing (j-1.
The instrument preset function performs a processor test, but does not affect
CAL data. Pressing C-1 clears both the input and output buffers, but does
not clear trace B. The amplitude values of trace C are set to the reference
level. Amplitude-correction factors are turned off. Limit-line testing is turned
off, but the limit-line tables remain in spectrum analyzer memory. The status
byte is set to 0. Instrument preset affects all operating modes. See the key
description for (jj] for more information about other operating modes.
Pressing [m] erases all “on time” functions-ONCYCLE, ONDELAY,
ONEOS, ONMKR, ONSRQ, ONSWP, ONTIME, and TRMATH. These are remote
programming commands. See the HP 8590 E-Series and L-Series Spectrum
Analyzer and HP 8591C Cable TV Analyzr Programmer’s ciuide for more
information.
Note
Turning the spectrum analyzer on performs an instrument preset. Turning on
the spectrum analyzer also fetches CAL data; completes a processor test; clears
trace B, trace C, and both the input and output buffers; turns off amplitude
correction factors; turns off limit-line testing; and sets the status byte to 0.
The last state of the spectrum analyzer (before it was switched off) is recalled,
unless IP has been set by the POWER ON function.

allows the spectrum-analyzer mode only to be preset. Table 7-12 lists the
conditions affected by the PRESET SPECTRUM function. Other operating
modes will not be affected. See the description of the CMODE) key.
In addition, pressing PRESET SPECTRUM erases user-generated graphics and
blanks the active-function block that is on the spectrum analyzer screen.
Pressing PRESET SPECTRUM disposes of ONEOS, ONSWP, and TRMATH. These
are remote programming commands; see the HP 8590 E-Series and L-Series
Spectrum Analyzer and HP 8591 C Cable TV Analyzer Programmer’s Guide for
