Section 6 Performance Tests
(5) Procedure
(a) Calibration of signal-generator 69269A
Step Procedure
1
Set the 69269A as shown below:
OUTPUT FREQ ...................................... 50 MHz
OUTPUT LEVEL ................................... –6 dBm
2
Connect the 69269A output to the power sensor input with a coaxial cable.
3 Read the power meter display.
4
Change the 69269A output frequency as shown in the tables on the next page and read the
power meter display with level at 50 MHz as reference. This data is the calibration data.
(b) Readout of measured amplitude deviation (frequency
response)
Step Procedure
1
Connect the 69269A OUTPUT to the MS8608A/MS8609A RF Input with a coaxial cable.
2
Press the MS8608A/MS8609A Preset key.
3
Perform all calibration. (Refer to Section 8 of Vol.2)
4 Set the MS8608A/MS8609A as shown below:
Center Freq .............................................. 50 MHz
Span ........................................................ 200 kHz
Reference Level .................................... –10 dBm
5
Press the
→
CF key.
6
Set the marker mode to delta marker.
7 Set the MS8608A/MS8609A center frequency as shown in the tables on the next page, then
obtain the deviation from the formula below by reading the delta marker level at each fre-
quency.
Deviation = Delta marker level reading - Measurement frequency calibration value
For Band 1- and 1+, the pre-selector is peaked. (Refer to Section 8 of Vol.2)
