3.7.10 Sensitivity with Internal Mixer.

3.7.11 Sensitivity with External Mixer.

3.7.12  Frequency Response. When tuned to the specified frequency range, with attenuator set at

10 dB, the analyzer shall have the following:

3.7.13  Frequency Response with Internal Mixer.

3.7.14  Frequency Response with External Mixer.

3.7.15 Sideband Noise.  The Sideband noise shall be -86 dBc/Hz or less at 10 kHz offset from center frequency and in the lowest harmonic mixing mode.

3.7.16 Single Input Range.  The minimum amplitude reference level range shall be from -115 dBm to +30 dBm with a safe input of +30 dBm in the log mode or 1 Watt in the linear mode.

3.7.17  Input Attenuator Accuracy.  The input Attenuator shall have a minimum range of 0-60 dB

with front panel selectable steps of 10 dB attenuator.  The attenuator accuracy shall not exceed

3.0 dB over 60 dB range from 0-18 GHz, and 6.0 dB over the 60 dB range overall from 18-21

GHz.

3.7.18  RF Input Connector.  For frequencies up to 21 GHz, the RF input connector shall be compatible with the Type N connectors.  When mixers are used, the connection shall be through a combination of waveguide mixers, adapters and connectors.  The RF input connectors shall be compatible and mate nondestructively with WR 42 Flange UG-595/U (18-26.5 GHz), WR 28

Flange UG-500/U (26.5-40 GHz), and WR 22 Flange UG-383/U (33-50 GHz).
