R3765/67G Series Network Analyzer Operation Manual
10.9 Dynamic Level Accuracy
10-53
(2) Press [MEAS] and {TRANSMISSION}.
• Dynamic level accuracy at 50 MHz
(3) Press [CENTER], [5], [0] and [MHz] to set the center frequency to 50 MHz.
(4) Press [SPAN], [0] and [x1] to set the span to 0 MHz.
(5) Press [AVG], {IF RBW}, [1], [0], [0] and [x1] to set the RBW to 100 Hz.
(6) Press [MKR] to set the marker on.
(7) Press [MENU], {POWER}, [7] and [x1] to set the output level to 7 dBm.
Set a value as shown below according to the options used.
OPT 10: 2 dBm
OPT 10+OPT 12: 4 dBm
OPT 12: 9 dBm
(8) Set the step attenuator to 20 dB.
(9) Press [CAL] and {NORMALIZE (THRU)} to do normalization
(10) Set the step attenuator to 10 dB.
(11) Read out the marker level.
(12) Repeat steps (10) and (11) on each set level listed on Table 10-3.
Table 10-3 Check Point for the R3765BG/67BG
(13) For each set level, calculate the dynamic level error using the following formula:
(dynamic level error) = (measured value) - (Offset value)
NOTE: The offset value is a attenuator error at the reference point.
(Offset value)=(calibration factor of the attenuator at the reference point)-(calibration
factor of the attenuator at the set level)
• Dynamic level accuracy at 3.8 GHz
(14) Press [CENTER], [3], [.], [8] and [GHz] to set the center frequency to 3.8 GHz.
(15) Press [MRK], [3], [.], [8] and [GHz] to set the marker to 3.8 GHz.
