(3) Input sine wave A (f = 100 kHz) to IN30 and set #30 amplitude to 0.2 V_p-p.
(4) Measure #24, #23, #22 amplitudes VMGB1, VMGB2, and VMGB3 [V], and determine GMGB1, GMGB2, and GMGB3
using the following equation.
GMGB* = 20 × log (VMGB*/0.2) [dB]
(5) Set SW29 to A, input sine wave B (f = 100 kHz) to IN29, and set #29 amplitude to 0.2 V_p-p.
(6) Input sync signal to IN30.
(7) Measure #24, #23, #22 amplitudes VMBB1, VMBB2, and VMBB3 [V], and determine GMBB1, GMBB2, and GMBB3
using the following equation.
GMBB* = 20 × log (VMBB*/0.2) [dB]
(8) Set SW28 to A and SW29 to C, input sine wave B (f = 100 kHz), and set #28 amplitude to 0.2 V_p-p.
(9) Input sync signal to IN30.
(10) Measure #24, #23, #22 amplitudes VMRB1, VMRB2, and VMRB3 [V], and determine GMRB1, GMRB2, and GMRB3
using the following equation.
GMRB* = 20 × log (VMRB*/0.2) [dB]
