Description
Specifies the RF input attenuation.
Although the attenuation level in the X-series instruments can be specified using absolute values,
you can never set attenuation below 10 dB using the DN parameter. This is a safety feature to
prevent inadvertent setting of attenuation to a level that could damage the instrument.
Signal levels above +30 dBm will damage the instrument.
Format AT DB
: any real number or integer. If the value you enter is not a valid value for the
instrument you are using, it switches automatically to the closest valid setting.
Default unit: dB.
Range: 0 to 70 dB specified absolutely, and 10 to 70 dB in 10 dB steps. (If 8564E/EC or
8565E/EC is selected, the range is limited to 0 to 60 dB.)
