knob must be in the LOW FREQ position.
Second Integrator (TOP)
Sets the frequency of the second integrator (ƒ
PI
). This knob only selects the higher-frequency positions
(20 kHz - 2 MHz). To set ƒ
PI
to lower frequencies, this knob must be placed in the LOW FREQ position.
First Integrator (BOTTOM)
Sets the frequency of the second integrator (ƒ
PI
). This knob only selects the lower-frequency positions
(100 Hz - 10 kHz) and is only active if the SECOND INTEGRATOR (TOP) knob is in the LOW FREQ
position. To turn off the integrator, this knob must be placed in the OFF position and the FIRST
INTEGRATOR (TOP) knob must be in the LOW FREQ position.
Differential (TOP)
Sets the frequency of the differentiator (ƒ
D
). This knob only selects the higher-frequency positions (200
kHz - 10 MHz) and can turn off the differential by placing the switch in the OFF position. To set ƒ
D
to
lower frequencies, this knob must be placed in the LOW FREQ position.
Differential (BOTTOM)
Sets the frequency of the differentiator (ƒ
D
). This knob only selects the lower-frequency positions (500
Hz - 100 kHz) and is only active if the DIFFERENTIAL (TOP) knob is in the LOW FREQ position.
Differential Gain (25-turn trimpot)
Sets the maximum differential gain. 25-turn trimpot adjusts the gain from 5db to 15dB.
Auxiliary Servo: Gain (25-turn trimpot)
This trimpot sets the gain for the AUXILIARY SERVO OUTPUT. The Aux Servo is a pure integrator and
the gain ranges from 500 μs to 5 s. Full ccw sets gain to minimum (5 s), full cw sets gain to maximum
(500 µs).
