USERS DESCRIPTION OF FRONT PANEL CONTROL

1) Fuse holder - Easy access for replacement of 1.25A 250V fuse.

2) On-Off switch - Allows power to be applied to all outputs. Switch will light when on.

3) Power output terminals - This provides 30VAC center tapped at 15VAC - also provides output terminal

for positive and negative variable voltages.

4) Variable positive voltage control - Varies positive voltage from 0 to 20V at indicated output terminal.

5) Variable negative voltage control - Varies negative voltage from 0 to –20V at indicated output connector

pin.

6) Output terminals for 1kΩ and 100kΩ undedicated potentiometers.

7) 1kΩ undedicated potentiometer.

8) 100kΩ undedicated potentiometer.

9) Waveform selection control, square, triangle or sine generator waveforms.

10) Output terminals for all functions as stated, 4 pins per block.

11) Two logic switches - These are no bounce logic switches. Give one signal state change per move-

ment of switch.

12) Selects five ranges of frequencies from 10 to 100,000 hertz.

13) Fine frequency control - allows easy selection of desired function generator frequency.

14) Amplitude control - Controls the function generation output amplitude , 0-15Vpp.

15) DC offset control - controls the DC level of the generator output. DC may be varied +

10 volts from zero

level.

16) Input points for logic indicator LEDs. “A” input corresponds with A lamp, etc.

17) Logic indicators LEDs, total eight.

18) Eight data switches - Lets output of 5V or 0V depending on position.

19) Output terminals for all functions as stated, 4 pins per block.

20) Two breadboards containing a total of 1,660 tie points including 6 independent bus lines.
