∆GCS1

∆GCS2

Set SW41 → ON, V41 = 1.6V, V42 = 0V,

V54 = 0V and input SG1 (0 dB) to (TEST IN).

Then adjust V45 so that the non-inverted

output amplitude (black to white) at TP16 is

5 times the input signal amplitude and label

this as VI.

Input SG1 (–6 dB) to (TEST IN) and label the 4.0 6.0 — dB

non-inverted output amplitudes (black to white)

at TP15, TP16 and TP17 with V45 = VI as

VRST, VGST and VBST, and the inverted output

amplitudes as VRSTA, VGSTA and VBSTA,

respectively.

Next, label the non-inverted output amplitudes

(black to white) at TP15, TP16 and TP17 with

V45 = 5.0V as VRSM, VGSM and VBSM, and the

inverted output amplitudes as VRSMA, VGSMA

and VBSMA, respectively.

Next, label the non-inverted output amplitudes

(black to white) at TP15, TP16 and TP17 with

V45 = 1.6V as VRSN, VGSN and VBSN, and the

inverted output amplitudes as VRSNA, VGSNA

and VBSNA, respectively.

— –6.0 –4.0 dB

∆GCS1 = 20log (VRSM (A)/VRST (A))

= 20log (VGSM (A)/VGST (A))

= 20log (VBSM (A)/VBST (A))

∆GCS2 = 20log (VRSN (A)/VRST (A))

= 20log (VGSN (A)/VGST (A))

= 20log (VBSN (A)/VBST (A))

∆GRS1

∆GRS2

Set V42 = 0V, V54 = 0V, input SG1 (–6dB)

to (TEST IN), and set V45 = VI, SW46 → ON,

SW41 → ON, V41 = 1.6V and V46 = 5.0V.

Then label the non-inverted output amplitude

—

dB

(black to white) at TP15 as VRSTM and the

inverted output amplitude as VRSTMA.

Next, label the non-inverted output amplitude

(black to white) at TP15 with V46 = 1.6V as

VRSTN and the inverted output amplitude as

VRSTNA.

— –4.6 –2.5 dB

∆GRS1 = 20log (VRSTM (A)/VGST (A))

∆GRS2 = 20log (VRSTN (A)/VGST (A))

∆GBS1

∆GBS2

Set V42 = 0V, V54 = 0V, input SG1 (–6dB)

to (TEST IN), and set V45 = VI, SW47 → ON,

SW41 → ON, V41 = 1.6V and V47 = 5.0V.

Then label the non-inverted output amplitude

2.5 4.6

—

(black to white) at TP17 as VBSTM and the

inverted output amplitude as VBSTMA.

Next, label the non-inverted output amplitude

(black to white) at TP17 with V47 = 1.6V as

VBSTN and the inverted output amplitude as

VBSTNA.

— –4.6 –2.5 dB
