1. 1 With the instrument plugged into an ac power source and turned on apply a 1 kHz offset sine wave amplitude 1 Vpp offset 1 35V to the 1kQ input BNC 2 Triggering the oscilloscope on the sine wave input observe 1kHz square waves at each of the seven outputs The square waves should have about 50 duty cycle indicating that the input switching thresholds are nominally correct and very fast transition times typically 1 0ns rise and 0 6ns fall The phase may be shifted by 180 if an internal polarity control jumper is installed The outputs should switch between OV and 2 5V when driving 50Q loads The outputs should switch between OV and 5V when driving high impedance loads 3 Increase the sine wave frequency to 10MHZ and verify the square wave outputs remain about 50 duty cycle Calibration The CMOS distribution requires no calibration Stanford Research Systems CMOS Logic Distribution Amplifiers Circuit Description CMOS Distribution amplifier Refer to schematics FS3_1C This distribution amplifier is intended to distribute CMOS level logic pulses The amplifier has one input and seven outputs all on BNC connectors All inputs and outputs are logic levels Power The unit is powered from a universal input 24Vdc or 12Vdc power supply The power supply is regulated by a linear regulator U3 to provide a clean 5Vdc supply The current draw is normally very low except when operated at high input frequencies o

Broadband 50 Q Distribution Amplifiers Circuit Description Broadband Distribution amplifier Refer to schematics FS4_1B This distribution amplifier is intended to distribute broadband dc 100 MHz analog signals over 50Q or 75Q coax The amplifier has one input and seven outputs all on BNC connectors There are eight 150Q resistors that can be added in parallel with eight 75Q resistors to convert a unit from 75Q to 50Q R16 R103 R203 R303 R703 Power The unit operates from a floating 24Vdc power supply A virtual ground is created to split the supply into 12Vdc supplies The virtual ground is maintained by the op amp U1 which maintains the midpoint of the supplies at 0V by drawing current from either the 12V supply or the 12V supply to exactly balance the current drawn by the circuit The 12Vdc supplies are regulated to 10Vdc supplies by U2 and U3 The 10Vdc supplies provide power to the rest of the instrument The comparator U4 will turn the FAULT LED on if the 10Vdc supplies are not balanced Input The input is terminated by R15 for 75Q or R15 amp R16 for 50Q The input op amp US is protected by a series resistor R18 that is clamped to 3 5V by D1 D2 amp D3 Amplifier The input amplifier U5 is a high bandwidth current feedback op amp that operates off 10V power supplies The circuit operates with a nominal gain of x2 42 The output drives a PCB trace via a 14Q resistor R24 which is terminated in
