Amplitude / Y Scale 2
Agilent N8201A Performance Downconverter Synthetic Instrument Module, 250 kHz to 26.5 GHz 47
Attenuation
Allows you to adjust the input attenuation. Press Atten Step to set the attenuation step so
that attenuation will change in 2 dB or 10 dB increments. The N8201A input attenuator
reduces the power level of the input signal delivered to the input mixer. If set manually, the
attenuator is recoupled when Attenuation (Auto) is selected.
Attenuation is coupled to Reference Level, so adjusting the Reference Level may change
the Attenuation. The N8201A selects an Attenuation setting that is as small as possible
while keeping the Ref Level at or below the Max Mixer Lvl setting. The current value is
indicated by Atten at the top of the display. A # appears in front of Atten when Attenuation
(Man) is selected.
Key Path: AMPLITUDE / Y Scale
State Saved: Saved in Instrument State
Factory Preset: Auto Coupled, 10 dB (for external amplifier gain of 0 dB)
Resolution/Rounding/Truncation: The attenuation is resolved to 2 dB increments. If
the value is at least 0.5 dB over a value, then the next higher value is selected. Therefore,
10.4 selects 10, while 10.5 selects 12.
Range: 0 dB to 70 dB
Remote Command:
[:SENSe]:POWer[:RF]:ATTenuation <rel_power>
[:SENSe]:POWer[:RF]:ATTenuation?
[:SENSe]:POWer[:RF]:ATTenuation:AUTO OFF|ON|0|1
[:SENSe]:POWer[:RF]:ATTenuation:AUTO?
Remote Command Notes:
The Reference Level setting may be affected when the Attenuation is changed. See “Ref
Level" on page 46.
CAUTION
To prevent damage to the input mixer, do not exceed a power level of +30 dBm at the input.
To prevent signal compression, keep the power at the input mixer below 0 dBm (10 MHz -
200 MHz), below 3 dBm (200 MHz - 6.6 GHz), and below –2 dBm (6.6 GHz - 50.0 GHz). With
the attenuator set to Auto, a signal at or below the reference level results in a mixer level at
or below −10 dBm.
