PN: 10370-10386 Rev. B
MG362x1A MM
1.
Initial setup of the Measurement Receiver:
a.
Reset the receiver by pressing the
Preset
key.
b.
Press the
Freq
key, then select
Frequency Span
and enter 10 kHz.
c.
Press the
BW
key, then select
Manual
and enter 10 Hz.
2.
Setup the MG362x1A as follows:
a.
Press
FREQUENCY
to open the current frequency parameter for editing.
b.
Set F1 to the CW frequency indicated in the test record.
c.
Press
LEVEL
to open the current power level parameter for editing.
d.
Set L1 to –40 dBm.
3.
If measuring frequencies below 2400 MHz, connect the MG362x1A
RF Output
directly to the measuring
receiver’s
RF input
and skip to Step 7.
4.
If measuring frequencies above 2400 MHz, connect the MG362x1A
RF Output
to the mixer’s
R-input
port
and set up the LO as follows:
a.
Press
FREQUENCY
to open the current frequency parameter for editing.
b.
Set F1 to the LO CW frequency indicated in the test record.
c.
Set L1 based frequencies list:
10 GHz leave the power at +13 dBm.
10 GHz but
to 20 GHz set power to +12 dBm.
> 20 GHz set power to +6 dBm.
5.
Set up the measuring receiver as follows:
a.
Press the
Freq
key and enter the CW frequency listed in the test record.
b.
Press the
Offset
key, select the offset valve, enter 0.
c.
Read the measured value and calculate the line and mixer loss offset as follows:
d.
(Test record reading at –40 dBm for the current test frequency) – Receiver Reading = Offset
e.
The offset value should be a positive number.
f.
Press the
Offset
key and select
Offset On
.
g.
Select
Offset Value
and enter the offset value that was calculated above. The displayed reading on
the measuring receiver should be the test record reading at –40 dBm for the current test
frequency. If not, repeat steps b through e.
1.
On the MG362x1A, set L1 to the power level indicated in the test record starting with –55 dBm.
2.
Measure the relative output power level and record the reading into the test records.
3.
Repeat steps 8 and 9 for each of the test power levels listed in the test record for the current CW
frequency.
Note
If using the T2579 mixer box, moving the cables is not required because the T2579 box
automatically connects to the proper locations.
Note
When measuring frequencies above 2400 MHz, the LO, DUT, and measuring receiver should be
connected to the mixer and the measuring receiver should be set to measure 8.51 MHz.
Note
When making power level changes greater than 15 dB, the first measurement should be thrown out
to allow for the measuring receiver to auto range.
