10.9.1.3.2 B PORT Measurement for Dynamic Level Accuracy
(1) Connect two 3-dB attenuator, step attenuator using two RF cables between SOURCE and
B PORT shown in Figure 10-30.
Figure 10-30 Connections for B PORT Measurement for Dynamic Level Accuracy
(2) Press [MEAS] and {B/R} to set the B PORT measurement mode.
• 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}, [6] and [x1] to set the output level to 6 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 10-2.
(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)
