2. Connect the Model 3152 output to the oscilloscope input.
Use the 20 dB attenuator and set the oscilloscope input
impedance to 50S.
3. Set the oscilloscope and verify that the rise and fall times
are less than 6 ns. Verify that overshoot and ringing are less
than 5% of amplitude.
Sine Characteristics Specified Total Harmonic Distortion: <0.1% from 10.00Hz to
100.0KHz (with a 4000 point waveform).
Specified Harmonic Signals:
<5MHz, <10Vp-p, -50dBc
<5MHz, <16Vp-p, -45dBc
<10MHz, <10Vp-p, -40dBc
<10MHz, <16Vp-p, -35dBc
<50MHz, <10Vp-p, -28dBc
<50MHz, <16Vp-p, -23dBc
Equipment: Krohn-Hite 6900 (or equivalent) Distortion Analyzer,
RF Spectrum Analyzer, 50Ω feedthrough termination (or 20dB 50Ω
attenuator if required).
1. Connect the Model 3151 output to distortion analyzer
input.
2. Set the distortion analyzer to distortion measurements, set
the Model 3151 frequency setting, and verify the
distortion reading as below.
3. Configure the Model 3151 as follows:
Function: USER Waveform
Frequency: 10.00Hz
Amplitude: 5V
Remote Commands : :RES
:OUTP ON
:FUNC:MODE USER
:TRAC:DEF 4000
:TRAC:SEL 1
:FREQ:RAST 40e3
:VOLT5
Using WaveCAD, change the axis (Setup | Axis) to have 4000
points (0 to 3999) for the first 4 steps below and 1000 points (0 to
999) for step 5 below. Download a 1k or 4k sine waveform (Wave
| Sine | OK) into segment 1.
FREQ:RAST # of Points Frequency Distortion Reading
40e3 4000 10Hz < 0.1%
40e4 4000 100Hz < 0.1%
40e5 4000 1kHz < 0.1%
40e6 4000 10kHz < 0.1%
100e6 1000 100kHz < 0.1%
