a. Set the power meter frequency. From the N1914A front panel, press the Channel button, highlight the
Frequency field, and enter the frequency for both channels.
b. Note the displayed power for both channels.
c. Calculate the insertion loss as: Channel A power – Channel B power.
d. Record the insertion loss value for RF 1 OUT in the Test Record Card (see page 41 ).
RF IN to RF 2 OUT measurement
1. Move the Channel B power sensor to the M9360A RF 2 OUT port, using the right angle SMA and 3.5 mm
(m) to 3.5mm (m) adaptors.
2. Using the M9360A Soft Front Panel, enable Custom Settings and set the M9360A RF/LO Out to 2 (High
band).
3. Repeat steps 7.a. to 7.c. from RF IN to RF 1 OUT measurement in the above procedure.
4. Record the insertion loss value for RF 2 OUT in the Test Record Card (see page 41 ).
LO IN to LO 1 OUT measurement
1. Move the Channel A power sensor to the LO IN port on the M9360A.
2. Move the Channel B power sensor to the LO 1 OUT port on the M9360A, using the right angle SMA and
3.5 mm (m) to 3.5mm (m) adaptors.
3. Using the M9360A Soft Front Panel, set the M9360A RF/LO OUT to 1 (Low band).
4. Repeat steps 7.a. to 7.c. from RF IN to RF 1 OUT measurement in the above procedure.
5. Record the insertion loss value for LO 1 OUT in the Test Record Card (see page 41 ).
LO IN to LO 2 OUT measurement
1. Move the Channel B power sensor to the LO 2 OUT port on the M9360A, using the right angle SMA and
3.5 mm (m) to 3.5mm (m) adaptors.
