Distortions and Noise

 

When using the electronic attenuator, the

 

 

mechanical attenuator is also in-circuit. The full

 

 

mechanical attenuator range is availablea.

1 dB Gain Compression Point

 

The 1 dB compression point will be nominally

 

 

higher with the electronic attenuator “Enabled”

 

 

than with it not Enabled by the lossb , except with

 

 

high settings of electronic attenuationc.

Displayed Average Noise Level

 

Instrument Displayed Average Noise Level will

 

 

nominally be worse with the electronic attenuator

 

 

“Enabled” than with it not Enabled by the lossb.

Second Harmonic Distortion

 

Instrument Second Harmonic Distortion will

 

 

nominally be better in terms of the second

 

 

harmonic intercept (SHI) with the electronic

 

 

attenuator “Enabled” than with it not Enabled by

 

 

the lossb.

Third-order Intermodulation

 

Instrument TOI will nominally be better with the

electronic attenuator “Enabled” than with it not

 

 

Enabled by the lossb except for the combination of

 

 

high attenuation setting and high signal frequencyd

a.The electronic attenuator is calibrated for its frequency response only with the mechanical attenuator set to its preferred setting of 10 dB.

b.The loss of the electronic attenuator is nominally given by its attenuation plus its excess loss. That excess loss is nominally 2 dB from 0 − 500 MHz and increases by nominally another

1dB/GHz for frequencies above 500 MHz.

c.An additional compression mechanism is present at high electronic attenuator settings. The mechanism gives nominally 1 dB compression at +20 dBm at the internal electronic attenua- tor input. The compression threshold at the RF input is higher than that at the internal elec- tronic attenuator input by the mechanical attenuation. The mechanism has negligible effect for electronic attenuations of 0 through 14 dB.

d.The TOI performance improvement due to electronic attenuator loss is limited at high fre- quencies, such that the TOI reaches a limit of nominally +45 dBm at 3.6 GHz, with the pre- ferred mechanical attenuator setting of 10 dB, and the maximum electronic attenuation of

24dB. The TOI will change in direct proportion to changes in mechanical attenuation.
