ACCEPTANCE TESTING
7-5
Recommended test equipment
The test equipment recommended for acceptance testing is shown below. Alternative equipment
may be used provided it complies with the stated minimum specification.
Recommended test equipment
Description Minimum specification Example

* Option 037 is necessary to measure SSB phase noise.
# The 6932 sensor is required only when testing instruments fitted with Option 3 (high power).
## 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.
