†
IFR Ltd. was previously known as Marconi Instruments Ltd.
* Option 037 is necessary to measure SSB phase noise.
#
If the receiver and down-converter are not available, an alternative procedure to ensure
attenuator pad accuracy using a power meter is given.
** The distortion option of the 2305 Modulation Meter allows modulation distortion tests to be
carried out with greater ease. If a 2305 with the distortion option is not available, the audio
analyzer may be connected to the modulation meter LF output and set to measure distortion.
