momentarily shorting TP2. Shorting TP3 reduces the level required to trip the
Attenuator/ RPP, so it trips on the Generator's own output_ This provides a convenient
way to verify the operation of the entire trip circuitry, although at a reduced trip level.
To check the trip function with TP3 shorted, it is best to program the Generator to an
output level of+ 10 dBm; then, program itforfixed amplitude range ([SPCL][9J[ I]). This
allows the level to be varied from a low value up to the maximum value without any
transients that might outherwise trip the RPP. Then, starting at a low level, such as -10
dBM (with the RPP reset), increase (EDIT) the UUT level in I d B steps until the RPP
trips. RPP trip normally occurs between + 10 and +
