In the GATE SETTINGS submenu, all settings are made
which are necessary for ’gated sweep’ operation.
On switching to the time domain, the GATE DELAY and
GATE LENGTH times are represented by horizontal time
lines which allow simple adjustment of the gate time.
The softkeys GATE EXTERN and GATE RF POWER provide
alternative settings, only one of them can be active at one
time.

LEVEL
The GATE LEVEL softkey activates the entry window for defining the
threshold value of the external gate signal.
The threshold can be set between -5V and +5V.

GATE MODE
LEVEL EDGE
The GATE MODE LEVEL/EDGE softkey selects the trigger mode. The sweep
mode GATE can be operated either as level or as edge triggered.
For level triggering, the GATE LENGTH softkey is deactivated and can not be
used.

GATE POL
POS NEG
The GATE POL softkey determines the polarity of the GATE control line.
If level triggering with GATE POL POS is set, the sweep is stopped when the
gate signal is a logic ´ 0 ' (input signal < gate level) at the EXT
TRIGGER/GATE input and then, when the gate signal goes to a logic ' 1 ', the
sweep is continued after a delay time of GATE DELAY.
In the case of edge triggering, the sweep is continued on a ' 0 ' to ' 1'
transition for the duration of GATE LENGTH after a delay (GATE DELAY) has
elapsed.
