|G|
GA TE (ONj OFF) j [ ](1 j0) j?;
T urns on or o the video-gating function. When the video-gating
function is turned on, the sp ectrum analyzer activ ates the video gate
circuitry according to the parameters con trolled b y gate length (GL),
gate dela y (GD), and the gate trigger input.
OUTPUT 718;"GATE ON;"
Query resp onse: (1 j 0)<LF with EOI >
OUTPUT 718;"GATE ?;"
ENTER 718;Gate_on
GA TECTL (EDGE j LEVEL)j ?;
Selects b et w een the edge and the lev el mo de for video-gate function. In
the edge mo de, a sp ecied trigger edge starts the gate dela y timer that
in turn starts the gate length timer. In the lev el mo de, the gate follows
the trigger input lev el.
OUTPUT 718;"GATECTL LEVEL;"
Query Resp onse: (EDGE j LEVEL)<LF with EOI >
OUTPUT 718;"GATECTL?;"
ENTER 718;Gate_cntrl$
GD <n um b er>< time units >j ?;
Sets the dela y time from when the gate trigger o ccurs to when the gate
is turned on. GD applies only if GA TECTL is set to EDGE.
OUTPUT 718;"GD 20US;"
Query Resp onse: <n um b er>< LF with EOI >
OUTPUT 718;"GD?;"
ENTER 718;Gate_delay
