Description

Specifies the RF input attenuation.

Although the attenuation level in the X-series of analyzers can be specified using absolute values, you can never set attenuation below 10 dB using the DOWN steps. This is a safety feature to prevent inadvertent setting of attenuation to a level that could damage the analyzer.

NOTE	In PXA/MXA, the auto attenuation range is 6-70 dB and in EXA, it is 6-60 dB.
CAUTION	Signal levels above +30 dBm will damage the signal analyzer.
NOTE	You cannot step down below 10 dB. To set levels below 10 dB, you must specify
	the attenuation absolutely. For example, to set attenuation to 0 dB, you must use
	the command AT 0DB.
