4 8494/95/96G/H Operating And Service Manual

Overview

Table 3 8496G/H Attenuator Switching Order

Each solenoid requires a drive of 20 to 30 V with a switching current of

approximately 125 mA

at 24 V dc per section. The solenoid switching time

is less than 20 milliseconds including settling time. Once switched, the

solenoid plungers are held in place by permanent magnets and the solenoid

plungers automatically disconnect the selected coil drive and connect the

opposite coil drive (see Figure 1 and Figure 2). This simplifies the coil driver

circuit design and reduces the amount of heat dissipated by the solenoid

coils since the solenoid coils are energized only for the 20 milliseconds

switching time.
