Electrical Characteristics Test Method (M61323SP)
Circuit Current 1
No signal. Measure the total circuit current as I
Circuit Current 2
No signal. Measure the total circuit current as I
Output DC Voltage 1, 2
Set SW13 to GND (or OPEN), measure the DC voltage of TP31 (TP28, TP25) when there is no signal input.
The DC voltage is as vdc1 (vdc2).
Output DC Voltage 3, 4
Measure the DC voltage TP23 same as "Output DC voltage 1, 2". The DC voltage is Vdc3 (Vdc4).
Maximum Allowable Input Level 1, 2
Set SW13 to GND, input SG1 to pin 2 only. Gradually increasing the SG1 amplitude, read the amplitude of the input
signal when the output waveform of TP31 is strained. The value is as Vimax1. In the same way, measure Vimax1 in
response to inputs in pin 4 and pin 6 only.
Then set SW13 to OPEN, measure Vimax2 in response to inputs in pin 10, 12 and 14 only.
