Turn on CAM with telecommand:
EPS 70 4F4F
Should see current consumption rise
by 13mA
mA
OK
25
Send ping to CAM with
telecommand:
CAM 50 XXXX
Should see pong in TM as a packet
from CAM with the ASCII translation
“CAM”
OK
26
Turn CAM back off with
telecommand:
EPS 70 5F5F
Should see current drop back to where
it was before step 24
mA
OK

Command S-Band into
telemetry mode with
DTMF tones “B*”, and
ensure that the DTMF
software is running with
the audio line connected.
The ICOM should be using
a narrow filter.
Command S-Band into
transponder mode with DTMF
tones “BA”
Wait for DTMF tone
telemetry, once every two
minutes. Power should be
around 1.6 watts, and
temperature should be
ambient to start with but
rise as S-band carrier is
used. Record all info from
three bursts
Carrier will jump up if control tones
are on

Using control tones on from a
handheld UHF transceiver,
transmit audio
S-band carrier should come up and
repeat audio via groundstation
OK

Command S-band carrier up using
DTMF tones “B0”
If possible measure S-band
frequency using frequency counter
and patch antenna
Command S-Band carrier down
using DTMF tones “B0”
Request a small thumbnail via
UHF using telecommand:
OBC 0D FF04
Signal should rise and current
consumption reach around 730mA
Frequency should be very close to
2401.84 MHz
Signal should drop and current should
return to 357mA
Current consumption should rise for a
minute or two to approximately
780mA and 320 packets should be
recieved
