Command S-Band carrier down
with DTMF tones “B0”
Should see signal level drop back to
noise level, and current back to
357mA
mA
OK
10
Turn live stream on down UHF
with telecommand:
OBC 18 FF04
Should see an acknowledge from
OBC, and then telemetry as it arrives
in the stack
OK
11
Check ACDS data in the nominal
mode beacon
Field strength should be static, and
field rate should be zero (may take a
few minutes to settle down)
Strength
OK

Note TCS temperatures
Should be close to ambient

Request the entire alarm stack on
UHF with the telecommand:
OBC 02 FF04
Command ACDS telemetry rate
increase with telecommand:
ACDS 01 010A
Should get alarm from ACDS with
ASCII translation “ACDS Normal
Operation” and a timestamp from
boot-up
Should see telemetry rate of ACDS
increase from every 30 seconds to
every 6 seconds
OK
OK

Command S-Band TNC on with
DTMF tones “B5” and make sure
that the ICOM is using a wide
filter
Request 100 picture packets via S-
Band with telecommand:
OBC 03 000C
Command S-Band TNC off with
DTMF tones “B5”
Should see the current consumption
rise by 27mA
Should see the acknowledge, and then
100 packets arrive while the signal is
up on the ICOM
Should see the current consumption
drop back to where it was before step
