Figure 7. Output power normalized response at –120 dBm.
8. Time from trigger input to amplitude settled within 0.2 dB (within the controlled temperature range) or
within 0.5 dB (at the full temperature range). Carrier frequency is not changing. Measurements made with
the M9036A embedded controller in an M9018A chassis.
9. Baseband offset amplitude settled within 0.2 dB. Baseband offset can be adjusted from 0 to –20 dB.
10. Mean time from IVI command to amplitude settled within 0.2 dB. Carrier frequency is not changing.
11. Specifications apply within the controlled temperature range. For temperatures outside this range,
absolute level accuracy degrades by ± 0.02 dB/°C.
