ELECTORICAL CHARACTERISTICS TEST

METHOD

Note) Omitted because the signal input pins and SW No. have been

described in the Electrical Characteristics Table. SWA shall take

side a unless otherwise noted.

ICC1, ICC2 Circuit current 1, circuit current 2 (no signal)

The conditions shall be as provided in the Electrical Characteristics

Table. When SW19 is assigned to GND (or OPEN), and SWA is

placed on side b, take measurements in ampere meter A and

specify the value to be Icc1 (or ICC2).

VDC1, VDC2 Output DC voltage 1, output DC voltage 2

When SW19 is assigned to GND (or OPEN), and no signal is input,

measure T.P.35 (T.P.30, T.P.27) output DC voltage. Specify the

voltage to be VDC1 (or VDC2).

VDC3, VDC4, Output DC voltage 3, output DC voltage 4

Measure the output DC voltage of T.P.25 in the same manner as in

VDC1 and VDC2, and specify the voltage to be VDC3 (VDC4).

Vimax1, Vimax2, maximum allowable input 1, maximum

allowable input 2

Assign SW19 to GND and input SG1 into pin 2 only. Gradually

increasing the SG1 amplitude, read the amplitude of the input

signal when the output waveform of T.P.35 is strained. The value is

specified to be Vimax1. In the same manner, measure Vimax 1 in

response to inputs into pin 5 and pin 7 only.

Then assign SW19 to OPEN, measure the values at inputs into pins

11 , 13 , and 16 only. Then specify the values to be Vimax2.

characteristics 1 (100 MHz)

characteristics 2 (100 MHz)

1. The conditions shall be as provided in the Electrical

Characteristics Table. This measurement shall use active probe.

2. Assign SW19 to GND and input SG2 into pin 2 only. When this is

the case, specify the output amplitude of T.P.35 to be VOR1.

In the same manner, specify the output to be VOR2 with SG4

input.

1. The conditions shall be as provided in the Electrical

Characteristics Table. This measurement shall take active probe.
