Atec Agilent-E8267D - Manual (Page 6)

1. Specifications apply in CW and list/step sweep modes over the 15 to 35 ºC temperature range, with attenuator hold off
(normal operating mode). Degradation outside this range, for ALC power levels > –5 dBm, is typically < 0.3 dB. In ramp sweep
mode (with Option 007), specifications are typical. For instruments with Type-N connectors (Option 1ED), specifications apply
to 18 GHz only. From 18 to 20 GHz, typical level accuracy degrades by 0.2 dB. Specifications do not apply above the
maximum specified power.
2. If external inputs are used, specification applies with input level
√ (I 2 + Q 2 ) = 0.3 V rms and I/Q modulator attenuation is
internally optimized based on input levels.
3. Measured with symbol rate > 10 kHz and power ≤ 0 dBm.
4. Relative to ALC on, after power search is executed. When applying external I/Q signals with ALC off, output level will vary
directly with I/Q input level.
5. Options 532 and 544: 0.02 dB/°C (typ) above 2 GHz.
6. Compatible with Agilent EPM Series (E4418B and E4419B) power meters.
