Antenna System Delay Commands - Arbiter Systems 1092A Operation Manual

10.2 Command Set
Set Alarm Time Mark
Command: ddd:hh:mm:ss(.ss)OU(OL)
OU sets the time at which the clock issues the programmable pulse, in the UTC timezone. OL sets
the time at which the clock issues the programmable pulse, in the Local timezone. If ddd is set to
0, the pulse will repeat daily at the specified time. If ddd is set from 001 to 366, the output pulse
will be generated at the next occurrence of the specified time and date.
C
Response:
Format: ddd = day of year (1 through 366)
hh = hour (0 through 23)
mm = minute (0 through 59)
ss = second (0 through 59)
(.ss) = fractional seconds in 0.01 increments (00 through 99)
OU = UTC time (OL for Local time)
Set Pulse Output to Slow Code
Command: nCM
nCM configures the pulse output to slow code. Slow Code pulse output is held high and goes low
for six seconds on the day, four seconds on the hour and two seconds on the minute.
C
Response:
Format: n = 0, Slow Code off
n = 1, UTC Slow Code
n = 2, Local Slow Code
Set Pulse Polarity
Command: nPP
nPP sets the programmable pulse output polarity (i.e. TTL/CMOS high or low), where n = 0
sets pulse polarity to positive, and n = 1 sets the pulse polarity to negative. Positive means that
the output voltage is held low until the beginning of the pulse period, at which time it goes high.
Negative means that the output voltage is held high until the beginning of the pulse period, at
which time it goes low.

Antenna System Delay Commands

Set Antenna Delay
Command: nnnnnnDA
nnnnnnDA sets antenna system delay compensation value. NOTE: Factory default setting for the
standard 15-meter (50-foot) cable is 60 ns. Time range is from 0 to 999999 nanoseconds. The exact
syntax for a 60-ns delay is 60DA. See Section 4.4.1 for information on calculating cable delay.
