TRIGGER... EXT RETRIGGER
INHIBIT
Sets the number of chips by which a restart is
delayed after a trigger event. If the TRIGGER MODE
RETRIG was selected, every further trigger signal
restarts the GPS signal. This restart can be inhibited
for the number of chips that have been entered.
Example:
Entry of 20460 chips (corresponds to a navigation
data bit) causes every further trigger signal to be
ignored for the duration of 20460 chips after the last
trigger event.
IEC/IEEE-bus command :SOUR:GPS:TRIG:INH
20460
TRIGGER OUT 1/2
Selects the signals for outputs TRIGOUT 1 and
TRIGOUT 2 of the PARDATA connector.
C/A_CODE Marker signal for every C/A-code
sequence (1023 chips).
IEC/IEEE-bus command:
:SOUR:GPS:TRIG:OUTP1 CODE
NAVBIT Marker signal for every navigation data
bit (20460 chips).
IEC/IEEE-bus command:
:SOUR:GPS:TRIG:OUTP1 NBIT
NAVWORD Marker signal for every navigation data
word (30 bits).
IEC/IEEE-bus command:
:SOUR:GPS:TRIG:OUTP1 NWOR
SUBFRAME Marker signal for every navigation
subframe (corresponds to 10
words).
IEC/IEEE-bus command:
:SOUR:GPS:TRIG:OUTP1 SFR
FRAME Marker signal for every navigation
frame (corresponds to 5
subframes).
IEC/IEEE-bus command:
:SOUR:GPS:TRIG:OUTP1 FRAM
TRIGGER OUT 1/2 POL
Selects the polarity of the signals at the TRIGOUT 1
and TRIGOUT 2 outputs of the PARDATA connector.
IEC/IEEE-bus command :SOUR:GPS:OUTP2:POL
POS
TRIGGER OUT 1/2
DELAY
Enters the number of chips by which the selected
trigger output signal is delayed.
