WIDE BAND ANALOG SWITCH

ELECTRICAL CHARACTERISTICS TEST METHOD (Pin No is FP)

It omits the SW.No accorded with signal input pin because it is already

written in Table .

SW A,SW1,SW3,SW5 is in side a if there is not defined specially.

Icc1,Icc2,Circuit current(no signal)

The condition is shown as Table . Set SW19 to GND(or OPEN) and SW A

to side b, measure the current by current meter A. The current is as

Icc1(Icc2).

VDC1,VDC2 Output DC voltage

Set SW19 to GND (or OPEN), measure the DC voltage of

T.P.35(T.P.30,T.P.27) when there is no signal input.The DC voltage is as

VDC1(or VDC2).

VDC3,VDC4 Output DC voltage

Measure the DC voltage of T.P.25 same as Table, the DC voltage is as

VDC3(or VDC4).

Vimax1,Vimax2 Maximum allowable Input

Set SW19 to GND, SG1 as the input signal of Pin 2.Rising up the

amplitude of SG1 slowly, read the amplitude of input signal when the output

waveform is distorted. The amplitude is as Vimax1. And measure Vimax1

when SG2 as the input signal of Pin 5,Pin 7 in same way. Next, set SW to

OPEN, measure Vimax2 when SG2 as the input signal of Pin11, 13, 16.

Gv1, Gv1,GV2, GV2

1. The condition is shown as Table .

2. Set SW19 to GND, SG2 as the input signal of Pin 2. At this time, read the

amplitude output from T.P 35. The amplitude is as VOR1.

3. Voltage gain Gv1 is

GV 1= 20 LOG VO R 1 [Vp-p] [dB]

0.7 [Vp-p]

4. The method as same as 2 and 3, measure the voltage gain Gv1 when

SG2 as the input signal of Pin 5, 7.

5. The difference of each channel relative voltage gain is as Gv1.

6. Set SW19 to OPEN, measure Gv2, Gv12 in the same way.

Gv3,Gv4,Voltage gain

1. The condition is shown as Table . This test is by active probe.

2. Measure the amplitude output from T.P.25.

3. Measure the GV3,GV4 by the same way as Gv1, Gv1,Gv2, Gv2.

Fc1, Fc1,Fc2, Fc2

1. The condition is shown as Table . This test is by active probe.

2. Set SW19 to GND, SG2 as the input signal of Pin 2. Measure the

amplitude output from T.P.35.The amplitude is as VOR1.By the same way,

measure the output when SG4 is as input signal of Pin 2, the output is as

VOR2.

3. The frequency characteristic Fc1 is

VO R2 [Vp-p]

FC1 = 20 LOG

[dB]

VO R1 [Vp-p]

4. The method as same as 2 and 3, measure the frequency Fc1 when input

signal to Pin 5, 7.

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

Fc1.

6. Set SW19 to OPEN, measure Fc2, Fc2.

Fc3,Fc4 Frequency characteristic

By the same way as Table measure the Fc3, Fc4 when SG5 of input

signal.

C.T.I.1,C.T.I.2 Crosstalk between two Input

1. The condition is shown as Table. This test is by active prove.

2. Set SW19 to GND, SG3 as the input signal of Pin 2. Measure the

amplitude output from T.P.35.The amplitude is as VOR3.

3. Set SW19 to OPEN, measure the amplitude output from T.P.35. The

amplitude is as VOR3'.

4. The crosstalk between two inputs C.T.I.1 is

VO R3' [Vp-p]

C.T.I.1 = 20 LOG

[dB]

VO R3 [Vp-p]

5. By the same way, measure the crosstalk between two inputs when SG3

as the input signal of Pin5, Pin 7.

6. Next, set SW19 to OPEN, SG3 as the input signal of Pin 11, measure

the amplitude output from T.P.35. The amplitude is as VOR4.

7. Set SW19 to GND, measure the amplitude output from T.P.35. The

amplitude is as VOR4'.

8. The crosstalk between two inputs C.T.I.2 is

C.T.I.2 = 20 LOG VO R4'[Vp-p] [dB]

VO R4[Vp-p]

9. By the same way, measure the crosstalk between channels when SG3

as the input signal of Pin 13,16.

C.T.I.3,C.T.I.4 Crosstalk between two input

Set SG4 as the input signal, and then the same method as Table, measure

C.T.I.3, C.T.I.4.

C.T.C.1,C.T.C.2 Crosstalk between channel

1. The condition is as Table .This test is by active prove.

2. Set SW19 to GND, SG3 as the input signal of Pin 2. Measure the

amplitude output from T.P.35. The amplitude is as VOR5.

3. Next, measure T.P.30, T.P.27 in the same state, and the amplitude is as
