UM9900A/3

Adjacent Channel Rejection (ACR)

ACR performance is limited by local oscillator phase-noise.

using the on-board VCO. Enhanced performance can be achieved using an external, low noise,

main LO.

Intermodulation

Typically greater than >65dB tested as EN 300 113.

Spurious Response Rejection

A front-end SAW filter is not provided on the default configuration EV9900A so spurious response

rejection is not guaranteed. However the option to fit a filter to reject such responses (type

selected by user) is available. The resulting performance will depend upon the operating band

used and the particular rejection characteristics of the chosen filter.

Blocking or Desensitisation

Blocking performance is approx. 86dB.
