7 Specifications apply over the 15 to 35ºC temperature
range, with attenuator lock off (normal operating
mode). Degradation outside this range, for ALC power
levels > -10 dBm, is typically < 0.3 dB.
For instruments with type-N connectors (Option 1ED),
specifications are degraded typically 0.2 dB above
18 GHz. Level accuracy is not specified below -110 dBm.
8 Compatible with Agilent Technologies EPM Series
(E4418B and E4419B) power meters.
9 Specifications for harmonics beyond maximum
instrument frequencies are typical.
