VCG — Voltage Controlled Generator
Up to 1000:1 frequency change (linear mode) or up to
10,000:1 change (logarithmic mode) with external 0 to
+ AV signal. Upper and lower frequencies limited to
maximum and minimum of selected range.
Slew Rate: 2% of range per из (linear); 0 to 100% of
range in 20 ms (logarithmic).
Linearity: +0.5% through x 100K range; =2% on
х 1М range.
Іприі |тредапсе: 2 КО.
Sweep
Main generator is frequency modulated by internal
sweep generator. Main generator frequency
repeatedly rises from frequency set by dial and range
button to frequency set by sweep stop knob.
Sweep Mode: Linear (3 decades max) or logarithmic
(4 decades max).
Sweep Rate: 30 ms to 1 min. (nominal) continuously
adjustable.
Sweep Width: Up to 1:1000 (linear) or 1:10,000
(logarithmic) continuously adjustable.
Sweep Output
Ramp waveform output with 4М peak into open circuit.
Source impedance 600Q. For use as a horizontal drive
signal.
Trigger and Gate
Input: TTL compatible levels.
Pulse Width: 50 ns minimum.
Repetition Rate: 4 MHz maximum.
