Calibration Manual
Calibration Procedure: 3 GHz Levelled Sine Function: HF Flatness (9530 only)
Repeat the process using the Cal. Point voltage levels in the Targets 1 - 5 sequence for
each of these frequency points, for a total of 75 calibration steps:
124
1. 9500B: Ensure that the 9500B is in HEAD CAL, Sine, 3 GHz Sine mode, FLAT.
2. The following process takes you through all TARGETs in Table 31. The process
sequentially calibrates all amplitudes at one frequency before repeating the same
amplitude calibration points at the next frequency step.
3. 9500B: Set Output ON.
4. Power Meter: Select a range that gives an on-scale reading.
5. Adjust the 9500B's output amplitude to give a reading equal to Target Amplitude
on the measuring device. The conversion from power to pk-pk voltage is pk-pk
Voltage = √ (power)
6. Press ACCEPT CALIB.
7. Select the next TARGET and return to step 4; repeat until no TARGETs remain.
8. Press NEXT FREQ then select TARGET 1 and return to step 4; repeat until no
TARGETs remain.
