MEASUREMENT METHOD
G1
Vertical Ramp Amplitude
A
Measure the amplitude of the vertical ramp wave on #49.
G2
Vertical Amplification
A
G3
Vertical Amp Maximum
Output Voltage
A
G4
Vertical Amp Minimum
Output Voltage
A
Set #53 and #54 to open.
Set the subaddress (17) data to (80).
Connect #54 to an external power supply. When the voltage is varied from 4.0 V to 6.0 V,
measure the vertical amplification on the #53 voltage. (GV) (VH53) (VL53)
G5
Vertical Amp Maximum
Output Current
A
Set #53 and #54 to open.
Apply 7 V to #54 from an external source.
Insert an ammeter between #53 and GND, and measure the current.
G6
Vertical NF Sawtooth Wave
Amplitude
A
Measure the amplitude of the #54 waveform (vertical sawtooth waveform).
G7
Vertical Amplitude Range
A
When the subaddress (17) data are set to (MIN) and (MAX), measure the amplitudes of the #54 waveform (vertical sawtooth waveform) VP54 (00) and
VP54 (FC).
