15.3 Performance Test
WF1967/WF1968 15-6
15.3.2 Sine Wave Amplitude Accuracy Test
Connection:
FCTN OUT → Digital multi-meter (AC voltage TrueRMS measurement)
Use a coaxial cable.
Setting: The following table shows the amplitude after setting initialization. (Frequency
is set to 1kHz).
Measurement: Measure the output voltage for each waveform as the effective value.
Judgment:
It is normal when the value falls within the following table.
Amplitude setting (load open value) Rating range
20Vp-p (7.071Vrms) 7.000Vrms to 7.142Vrms
5Vp-p (1.768Vrms) 1.749Vrms to 1.786Vrms
3Vp-p (1.061Vrms) 1.049Vrms to 1.072Vrms
1Vp-p (353.6mVrms) 349.3Vrms to 357.8mVrms
0.3Vp-p (106.1mVrms) 104.3mVrms to 107.8mVrms
0.1Vp-p (35.36mVrms) 34.29mVrms to 36.42mVrms
0.02Vp-p (7.071mVrms) 6.293mVrms to 7.849mVrms
15.3.3 DC Offset Accuracy Test

DC only
Connection: FCTN
OUT → Digital multi-meter (DC voltage measurement)
Setting: Set the waveform to DC after setting initialization. The following table shows
the DC offset.
Measurement: Measure the output voltage as DC.
Judgment: It is normal when the value falls within the following table.
DC offset setting (load open
value)
Rating range
±10V ±9.890V to ±10.110V
±3V ±2.960V to ±3.040V
±1V ±0.9800V to ±1.0200V
±0.3V ±0.2870V to ±0.3130V
0V -10.00mV to +10.00mV

AC+DC
Connection:
FCTN OUT → Digital multi-meter (DC voltage measurement)
Setting: Set the oscillation mode to BURST, burst mode to GATE, trigger to external
Off (the oscillation of sine wave is stopped at 0 degree) after setting
initialization.
The following table shows the amplitude. DC offset setting is left to 0 V.
Measurement: Measure the output voltage as DC.
Judgment: It is normal when the value falls within the following table.
Amplitude setting (load open value) Rating range
6.4Vp-p -42.00mV to +42.00mV
3.5Vp-p -27.50mV to +27.50mV
0.7Vp-p -13.50mV to +13.50mV
