Absolute level accuracy in CW mode

(ALC on)

External reference input +21 to –60 dBm < –60 to –110 dBm < –110 to –127 dBm

9 to 100 kHz ± 0.6 dB, typical ± 0.9 dB, typical

100 kHz to 5 MHz ± 0.8 dB ± 0.9 dB

> 5 MHz to 3 GHz ± 0.6 dB ± 0.8 dB ± 0.5 dB, typical

> 3 to 6 GHz ± 0.6 dB ± 1.1 dB ± 0.6 dB, typical

Absolute level accuracy in CW mode (ALC off, power search run, relative to ALC on)

9 kHz to 6 GHz ± 0.15 dB, typical

Absolute level accuracy in digital I/Q mode (N5172B only)

(ALC on, relative to CW, W-CDMA 1 DPCH configuration < +10 dBm)

9 kHz to 6 GHz ± 0.25 dB

1. Quoted speciﬁ cations between 20 °C and 30 °C. For temperatures outside this range, absolute level accuracy degrades by 0.01 dB/°C. Output power

may drift up to .003 dB per g/kg change in absolute humidity (nom).
