3 Additional Tests During Thermal Cycling

3.1 MIRO SMM Gunn Voltage Auto-control Test

1. Set the SMM Gunn Voltage Auto-control Disable/Enable to Disable.

2. Print out copy of the telemetry sheets and record the time the command was sent in the 
Unit History Log.

3. As the temperature is rising, note when the PLL loses lock. Loss of lock is defined as 
when the SMM_PLL_ERR is outside the range a < SMM_PLL_ERR < b.  When this 
occurs, print out copy of the telemetry sheets.  Note the time on the telemetry sheet which 
indicates the out of lock condition and record that time with comments in the Unit History 
Log.

4. Set the SMM Gunn Voltage Auto-control Disable/Enable to Enable.

5. Send a change mode command to set CTS/Dual Continuum Mode to force a calibration 
and a reset of the Gunn Voltage.

6. Repeat steps 1 through 5 for until the transition to maximum operating temperature is 
completed.

7. As the Science Workstation Files close on the hour, open the just closed file and locate 
CTS scans near the time the out of lock condition(s) was noted in the housekeeping 
telemetry.  Search for the first indication in the CTS science data that the Lock Alarm Bits 
changed from there lock state of (Bytes) 80 80 80 80 80 80.  These bytes can be seen at 
the bottom of the graph of each CTS scan.  Print out a cop of the graph.  Put this graph 
with the appropriate telemetry sheets for that particular out of lock condition.

3.2 MIRO Asteroid Mode Test

1. Change mode to Dual Continuum.

2. Calculate the current spacecraft time in seconds.  Add 900 seconds to this number.

3. Send the Asteroid Mode command with the following parameters:

Start Time = the final number calculated in step 2 above
  Number of CTS scans = 2
  LO Starting Frequency = 0

4. Sit back and wait.  The command will execute in about 15 minutes from the current time.  
It'll take about 8 minutes to take the data and 10 hours to get all this data out.
