System-related sidebands
≥ 30 kHz offset from CW signal ≤ –65 dBc + 20 Log N⁴
1. Not available in RBW < 1 kHz
2. Marker level to DANL > 25 dB, Span ≤ 1.5 GHz, RBW/Span ≥ 0.002
3. Frequency reference error = (aging rate x period of time since adjustment
+ settability + temperature stability)
4. N = LO harmonic mixing mode
5. RBW ≥1 kHz, 2 sweep points
6. 1 Hz to 300 Hz are only available in spans of ≤ 5 MHz. This bandwidth is
not usable when the tracking generator is turned on (Option 1DN).
7. Characteristic
8. Add 20 log(N) for frequencies > 6.7 GHz.
