Step attenuator (Option 1E1)

Options 520, 521, 532, and 540 0 dB and 5 dB to 115 dB in 10 dB steps

With Optimize S/N on

0 dB to 115 dB in 5 dB steps

Options 550 and 567 0 dB to 90 dB in 10 dB steps

Attenuator hold range

Minimum From –20 dBm to maximum speciﬁed output power with step attenuator in 0 dB position. Can be offset using

Option 1E1 attenuator.

1. The step attenuator provides coarse power attenuation to achieve low power levels. Fine power level adjustment is provided by the ALC (automatic level control)

within the attenuator hold range.

2. With attenuator in auto mode. Optimize S/N mode provides improved signal/noise performance and is included with Option 521 and Option 1EU models. Specs in

the following sections (such as level accuracy, spectral purity, modulation, etc) are only tested with Optimize S/N mode turned off.
