19. 2 The 400F FLis a solidstate average responding rms calibrated ac voltmeter It may also be usedas a wide band ac amplifier with switchable gain and switchable bandwidth Refer to Figure 4 1 for a functional circuit diagram of the instrument 4 3 BLOCK DIAGRAM DESCRIPTION 4 4 The voltage to be measured is applied to the input attenuator where it is either attenuated by 60 db or coupled directly tothe preamplifier The pre amplifier provides 10 db of gain for the input signal and applies it to the post attenuator The signal goes from the post attenuator to the 100 KHz LOW PASS filter which may be switched in to limit the bandwidth to signals from 20 Hz to 100 KHz The meter amplifier then amplifies the signal couples it to the meter bridge and supplies a signal tothe AC OUTPUT terminal The meter bridge rectifies the ac signal and applies it to meter M1 which indicates the rms value of input voltage The meter bridge also provides the ac feedback to the meter amplifier 4 5 SCHEMATIC THEORY 4 6 Refer to Figure 6 1 for the following discussion 4 7 INPUT ATTENUATOR 4 8 The input attenuator consists of an rc voltage divider and two reed relays On the 1 mv through ranges reed relay is energized by 26 v from wafer A of the RANGE switch S1 routing the input signal directlyto the preamplifier On all other ranges the 26 v is applied to relay A1K2 When A1K2 isclosed the input signal is
