Operating Manual EMI TEST RECEIVER ESIB7 - Rohde & Schwarz

Sweep Control - Analyzer
ESIB
GATE
DELAY
The GATE DELAY softkey activates the entry window for setting the delay
time between the gate signal and the continuation of the sweep.
This may be usefull in allowing for a delay between the gate signal and the
stabilization of an RF carrier.
Gate delay values can be selected between 1 µs and 100 s. The resolution is
dependent upon the absolute value of the delay time:
Gate delay Resolution
0 - 500 µs 1 µs
0.5 - 5 ms 5 µs
5 - 50 ms 50 µs
50 - 500 ms 500 µs
0.5 - 5 s 5 ms
5 - 50 s 50 ms
50 - 100 s 500 ms
In the time domain, a time line is displayed separated from the trigger point by
the gate delay time. This simplifies the adjustment of the necessary delay
time.
The values for GATE DELAY and GATE LENGTH are displayed by two time
lines. The duration of the active sweep for span > 0 (continuation of sweep:
GATE DELAY line, stopping of sweep: GATE LENGTH line) is described by
these two lines. A change in parameters causes a shift of the corresponding
line position. After switching to span > 0, the selected times for the gated
sweep are effective.
IEC-bus command
:[SENSe:]SWEep:EGATe:HOLDoff 100us
GATE
LENGTH
The GATE LENGTH softkey activates the entry window for defining the ESIB
sweep duration.
GATE LENGTH can be set to values between 1µs and 100 s. The resolution
is dependent upon the absolute value of the gate length:
Gate length Resolution
0 - 500 µs 1 µs
0.5 - 5 ms 5 µs
5 - 50 ms 50 µs
50 - 500 ms 500 µs
0.5 - 5 s 5 ms
5 - 50 s 50 ms
50 - 100 s 500 ms
In the time domain (ZERO SPAN), a time line is displayed separated from the
GATE DELAY time by the GATE LENGTH time.
The softkey is only available for the GATE MODE EDGE setting (edge
triggering). It is disabled for the GATE MODE LEVEL setting (level triggering).
IEC/IEEE-bus command :[SENSe:]SWEep:EGATe:LENGth 10ms
GATE
EXTERN
The GATE EXTERN softkey selects a signal applied to the EXT
TRIGGER/GATE connector on the rear panel of the instrument as a gate
source.

GATE
RF POWER
The GATE RF POWER softkey selects the internal RF power detector as a
gate source.
