Electrical Characteristics Test Method (M61323SP)

Circuit Current 1

No signal. Measure the total circuit current as ICC when supplying 3 VDC to pin 11.

Circuit Current 2

No signal. Measure the total circuit current as ICCSTBY when pin 11 connected to GND.

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.

Voltage Gain 1, 2

1. The conditions is as table.

2. Set SW13 to GND, input SG2 (0.7 VP-P) to pin 2 only. Read the output amplitude of TP31. The value is as VOR1.

3. Voltage gain GV1 is

GV1 = 20log

(dB)

0.7

VOR1 [VP-P]

4. In the same way, calculate GV1 in response to inputs in pin 4 and pin 6 only.

5. Then set SW13 to OPEN, measure GV2 in response to inputs in pin l0, 12 and 14 only.

Relative Voltage Gain 1, 2

1. Calculate relative voltage gain

∆G

V1 by the following formula.

∆G

V1 = GV1R − GV1G, GV1G − GV1B, GV1B − GV1R

2. In the same way, calculate

∆G

Voltage Gain 3, 4

1. The conditions is as table.

2. Read the output amplitude of TP23.

3. Calculate GV3, GV4 same as "Voltage gain 1".

Freq. Characteristic 1, 2/Relative Freq. Characteristic 1, 2

1. The conditions is as table. This measurement shall use active probe.

2. Set SW13 to GND, input SG4 (0.7 VP-P) to pin 2 only. Measure TP31 output amplitude as VOR1.

In the same way, input SG2 (0.7 VP-P) to pin 2 only. Measure TP31 output amplitude as VOR2.

3. Freq.characteristic1 FC1 is

FC1 = 20log

(dB)

VOR1 [VP-P]

VOR2 [VP-P]

4. In the same way, calculate FC1 in response to inputs in pin 4 and pin 6 only.

5. The difference between of each channel Freq.characteristic is as

∆F

C1.

6. Then set SW13 to OPEN, measure FC2 and ∆FC2 in response to inputs in pin 10, 12 and 14 only.
