TEST METHOD
(1) TP21 input : The following symbols (trigger pulse)
1
Vertical Trigger Input Shaping
Voltage
V_TH21
V
0.7 1.0 1.4 All PRESET values, all SW-A
2
Pulse Generator Circuit Clamping
Voltage
V_H22
V
3.8 4.0 4.2 All PRESET values, all SW-A
(2) Change the wave height of the trigger pulse on
TP21. Then read the wave height of the trigger
pulse when a timing pulse is output to TP22.
(1) TP21 input : The above trigger pulse
Wave height = 3 V
(2) Observe the TP22 and TP23 waveforms with an
oscilloscope. Measure the following V_H22 voltage:

Pulse Generator Circuit Shaping
Voltage 1
4
Pulse Generator Circuit Shaping
Voltage 2
V_M22
V_L22
5 Vertical Ramp Amplitude
V_P23
V
2.8 3.0 3.2 All PRESET values, all SW-A
Measure V_M22 as above.
V
0.9 1.0 1.1 All PRESET values, all SW-A
V_p-p
1.9 2.0 2.1 All PRESET values, all SW-A
Measure V_L22 as above.
(1) TP21 input : Same as 2 above (trigger pulse).
(2) Measure the TP23 waveform (vertical ramp)
amplitude.
Note: Unless otherwise specified in the bus data and SW mode column, use PRESET values
and W-A.
