6. Ensure that the L-Band input signal is being applied to the L-Band In port of the unit.
7. Allow the SSPB to warm up for 30 minutes, ensuring that all electrical specifications are met
(see
TABLE 2
at page 17).
7.4 FRONT PANEL OPERATION
Set-up the SSPB as follows:
1. Switch ON the main power source. The ‘

33.
NOTE:
In the gain or frequency value editor submenus, use the [
ç
] and [
è
] keys to select
the digit to be changed and the [
é
] and [
ê
] keys to change the value. Press the
[
Enter
] key to confirm the new value or the [
CLEAR]
key to return without the
changes.
6. Adjust the attenuation at the mixer input of the L-Band to C-Band up-converter module to
obtain a power level of – 20 dBm at the mixer input for the best signal to spurious ratio.
NOTE:
Input level + Attenuation = -20 dBm.
7. Adjust the gain of the L-Band to C-Band up-converter module to obtain the desired output
power level of the SSPB by following the sequence given in
Figure 6
at page 33.
8. If it is desired to switch the SSPB ‘ON’ or ‘OFF’, use the
[
é
]
and
[
ê
