Re marks: Re turns the cal fac tor value cur rently be ing used for the spec i fied sen -
sor. This will be a fixed value only when in MAN UAL cal fac tor mode,
oth er wise the value will de pend on the fre quency en tered when cal
source is FREQUENCY and the scaled fre quency when the cal source is
V/GHz.
CFVAL will not re turn the up dated Cal Fac tor Value if the sys tem is in
TR0 Trig ger Hold mode. That is, if you change the Cal Fac tor Fre -
quency and want to read back what the unit has set the Cal Fac tor to
when the sys tem is in TR0 mode, the sys tem will re turn the last Cal Fac -
tor value be fore you went into TR0 mode.
Also, you may have to wait for approximately 0.25 sec onds af ter you
change the Cal Fac tor Fre quency to read back the Cal Fac tor Value even
when not in TR0, as CFVAL is not up dated in stantly af ter you change
the Cal Fac tor Fre quency.
This re stric tion only ap plies to the CFVAL GPIB com mand and does not
ef fect any mea sure ment taken. If you are in TR0 mode, change the Cal
Fac tor Fre quency, and then take a mea sure ment the Cal fac tor will be
cal cu lated cor rectly.
