Specified Transition Time: 10ns typical (10% to 90% of ampli-
tude)
Specified Aberration: <5% of amplitude
Equipment: Oscilloscope, 20dB attenuator
1.
Configure the Model 3155 as follows:
Function:
Frequency:
Amplitude:
Remote Commands: :RES
2.
Connect the Model 3155 output to the oscilloscope i n -
put. Use the 20 dB attenuator and set the oscilloscope
input impedance to 50O.
3.
Set the oscilloscope and verify that the rise and fall
times are less than 10ns. Verify that overshoot and
ringing are less than 5% of amplitude.
Specified Total Harmonic Distortion: <0.05% from 10.00Hz
to 100.0kHz (with a 4000 point waveform).
Specified Harmonic Signals:
≤1MHz, -55dBc
≤5MHz, -40dBc
≤25MHz, -25dBc
Equipment: Krohn-Hite 6900B (or equivalent) Distortion An a-
lyzer, RF Spectrum Analyzer, 50Ω feedthrough termination (or
20dB 50Ω attenuator if required).
1.
Connect the Model 3155 output to the distortion ana-
lyzer input.
2.
Set the distortion analyzer to distortion measurements,
set the Model 3155 frequency setting, and verify the
distortion reading as below.
