Example of AC line synchronized output (1)Output burst on every AC cycle
Phase angle: 90°

Since the phase angle to be output burst synchronized AC line is based on the phase of L-N(A20) or the phase of L1-L2 (B63), If the ground reference plane is regarded as reference to【EUT LINE OUT】, N should be grounded in AC line input side in case of single-phase power
supply, or L2 should be grounded in case of 3-phase to output burst synchronizing with AC line
as shown in the above figures. (S should be grounded in case of 3-phase 3-line, etc.)
If your power supply is out of the above condition, synchronized output to AC line of the power
supply regarding the ground reference plane as reference cannot be guaranteed.
If AC line synchronization has to be set precisely, ensure relationship between AC line waveformand burst output with measurement.
If the actual phase angle deviates from the set value, adjust the input value. When outputting

21. WAVEFORM VERIFICATION

For observing waveform on an oscilloscope with connecting load resistance, the actual output
voltage and the input restriction of the oscilloscope should be checked previously.
The output voltage of the pulse to be observed can be found with applying the following〔Formula 1〕.

〔Formula 1〕

Vp

＝

R2
Z ＋ R2×

Vp：Output voltage of pulse
to be observed
R2：Load resistance
Z：Output impedance
E：Set voltage

In case of 50Ω load
The output impedance of the Unit is approximately 50Ω.If 00-00017A (50Ω load) is connected
and the set voltage is 4000V, The output voltage of the pulse to be observed Vp(50Ω) is;Vp(50Ω) ＝50Ω
50Ω＋ 50Ω

×

4000V

★

Vp(50Ω) ＝ 2000V

And as the attenuation ratio of 00-00017A is 100:1, the result is; 2000V÷100＝20V.
Check the input restriction of the oscilloscope and add a 50Ω attenuator if necessary.
In connection on the left page, with using the 20dB attenuator, 20V÷10＝2V.
In case of 1kΩ load
The output impedance of the Unit is approximately 50Ω.If 00-00018A (50Ω load) is connected
and the set voltage is 4000V, The output voltage of the pulse to be observed Vp(50Ω) is;Vp(1kΩ) ＝

50Ω＋ 1kΩ

×

4000V

★

Vp(1kΩ) ≒ 4000V

And as the attenuation ratio of 00-00018A is 1000:1, the result is; 4000V÷1000＝4V.
Check the input restriction of the oscilloscope and add a 50Ω attenuator if necessary.
In connection on the left page, with using the 20dB attenuator, 4 ÷10＝0.4 V★The range of the pulse output voltage to be observed actually is as follows depending on
specifications of the instrument.
