Description Of Front And Rear Panel Controls And Connectors - HP 3300A Technical Manual

Section II
(1) 115V/230V Slide Switch: S2 makes proper
connections in primary of input transformer for
selected input line voltage.
(2) Power Input Jack: J1, male receptacle for input
power cable.
(3) POWER Pushbutton: S1, a on-off switch which
illuminates when in the on position and power is
applied to the instrument.
(4) RANGE Switch: S3, a seven position rotary
switch which selects frequency determining
feedback parameters in the basic oscillatory
circuit.
(5) FREQUENCY Dial: R4, a linear dial which
controls frequency within the decade selected by
the RANGE Switch (4).
(6) Vernier Frequency Control: a fine frequency
adjustment knob.
(7) CHANNEL A Function Switch: S4, a four position
rotary switch which selects the desired OUTPUT
(10).

(8) CHANNEL B Function Switch: S5, a five position
rotary switch which selects the desired OUTPUT
(11).
(9) AMPLITUDE Controls: R12 and R9 attenuators
which vary the output level of the respective
channels.
(10) and (11)
OUTPUT Connectors: J2 and J3, BNC jacks for
connection to the respective outputs of the
function generator.
(12) FREQUENCY CONTROL: J5, a BNC jack for
applying external frequency control voltage.
(13) SYNC OUT: J4, a BNC jack for connection to
sync pulse which occurs at the crests of the sine
and triangle wave.
(14) FREQ DIAL-FREQ CONTROL Shorting Bar:
completes the circuits to the FREQUENCY Dial
for internal frequency control.
(15) Common Grounding Straps: ties circuit, output,
and shield grounds to power-line ground. Should
be connected unless otherwise specified.
