WIDE BAND ANALOG SWITCH

note ) It omits the SW.No accorded with signal input pin because it is already written in Table 1.

SW A is in side a if there is not defined specially.

note1) The condition is shown as Table 1. Set SW15 to GND(or OPEN) and SW A to side b, measure the

current by current meter A(or B). The current is as Icc1(Icc2,Icc3).

note2) Set SW15 to GND (or OPEN), measure the DC voltage of T.P.29(T.P.26,T.P.23) when there is no

signal input.The DC voltage is as VDC1(or VDC2).

note3) Measure the DC voltage of T.P.21 same as note2, the DC voltage is as VDC3(or VDC4).

note4) Set SW15 to GND, SG1 as the input signal of Pin 1.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 SG1 as the input signal of Pin 3,Pin 5 in same way.

Next, set SW 15 to OPEN, measure Vimax2 when SG1 as the input signal of Pin8, 10, 12.

note5) 1. The condition is shown as Table 1.

2. Set SW15 to GND, SG2 as the input signal of Pin 1. At this time, read the amplitude output from

T.P 29. The amplitude is as VOR1.

3. Voltage gain Gv1 is

VOR1 [Vp-p]

GV1= 20 LOG 0.7 [Vp-p]

[dB]

4. The method as same as 2 and 3, measure the voltage gain Gv1 when SG2 as the input signal of

Pin 3, 5.

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

∆Gv1=Gv1R-Gv1B,Gv1B-Gv1G,Gv1G-Gv1R

6. Set SW15 to OPEN, measure Gv2, ∆Gv2 in the same way.

note5') Voltage gain ∆Gv' is

∆Gv'=Gv1R-Gv2R,Gv1G-Gv2G,Gv1B-Gv2B

note6) 1. The condition is shown as table 1. This test is by active probe.

2. Measure the amplitude output from T.P.21.

3. Measure the GV3,GV4 by the same way as note5.

note7) 1. The condition is shown as table 1. This test is by active probe.

2. Set SW15 to GND, SG2 as the input signal of Pin 1. Measure the amplitude output from T.P.29.

The amplitude is as VOR1.By the same way, measure the output when SG4 is as input signal of

Pin 1, the output is as VOR2.

3. The frequency characteristic Fc1 is

VOR2 [Vp-p]

FC1 = 20 LOG VOR1 [Vp-p]

[dB]

4. The method as same as 2 and 3, measure the frequency Fc1 when input signal to Pin 3, 5.

5. The difference between of each channel frequency characteristic is as ∆Fc1.

6. Set SW15 to OPEN, measure Fc2,∆Fc2.

note8) By the same way as Note7 measure the Fc3, Fc4 when SG5 of input signal.

note9) 1. The condition is shown as Table1. This test is by active prove.

2. Set SW15 to GND, SG3 as the input signal of Pin 1. Measure the amplitude output from T.P.29.

The amplitude is as VOR3.

3. Set SW15 to OPEN, measure the amplitude output from T.P.29. The amplitude is as VOR3'.

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

VOR3' [Vp-p]

C.T.I.1= 20 LOG

[dB]

VOR3 [Vp-p]

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

signal of Pin3, Pin 5.
