10.4 Output Level Linearity
Testing procedure
Calibrate the power meter to zero.
Set the R3765/67G series as follows.
Center frequency : 50MHz
Span
: 0Hz
Output level
: AG type 7 dBm (2 dBm for OPT 10)
BG type -3 dBm (-8 dBm for OPT 10, -1 dBm for OPT 12,
-6 dBm for OPT 10 + OPT 12)
CG type 0 dBm (-5 dBm for OPT 10, OPT 10 + OPT 11 or 14,
-6 dBm for OPT 12 or 13,
-11 dBm for OPT 10 + OPT 12 or 13)
Sweep mode
: HOLD
Connect the power sensor to the output terminal and perform the measurement.
(Refer to Figure 10-4.)
For the AG type, connect the power sensor to the SOURCE terminal.
For the BG or CG type with OPT 11, OPT 13 or OPT 14 installed, connect the power
sensor to TEST PORT 1.
