Chapter 4 — Adjustment 4-8 RF Calibrator 50 MHz Frequency and 50 MHz/1 GHz Output Power
ML248xx, ML249xA MM PN: 13000-00164 Rev. K 4-7
7. Save the new 50 MHz and 1 GHz output level DAC values with the following command:
Write HCCSAV<50MHz Level Value>,<1GHz Level Value>,<Calibration date in the form
of MMDDYY>
Verifying Cal Data was Saved
1. To verify that calibration data is saved correctly, use the following command in the Send String box and
use the Query button, as shown in Figure 4-5:
Query HCCALDTO
2. The String Received should be:
HCCALDTO <Board SN>,<New 50MHz DAC value>,<New 1GHz DAC value>,<date>,<Freq
value>
3. Perform Section 3-7 “50 MHz Calibrator Power Level (All Models)” in Chapter 3 to verify the output
power is within specification.
4. Record results and calculations in Pmeas Calculation of Appendix A, “Test Records”.
