Amplitude Modulation (Option 14)
All amplitude modulation specifications apply at 50% depth, 1 kHz
rate, with RF level set 6 dB below maximum specified leveled
output power, unless otherwise noted. Amplitude Modulation is not
available <10 MHz with Option 22.
AM Depth (typical): 0-90% linear; 20 dB log
AM Bandwidth (3 dB):
DC to 50 kHz minimum
DC to 100 kHz typical
Flatness (DC to 10 kHz rates): ±0.3 dB
Accuracy: ±5%
Distortion: <5% typical
Incidental Phase Modulation (30% depth, 10 kHz rate):
<0.2 radians typical
External AM Input: Log AM or Linear AM input, rear-panel BNC,
50Ω input impedance. For internal modulation, add LF Generator
Option 23.
Sensitivity:
Log AM: Continuously variable from 0 dB per volt to
25 dB per volt.
Linear AM: Continuously variable from 0% per volt
to 100% per volt.
Maximum Input: ±1V
LF Generator (Option 23)
Two internal waveform generators are added, one providing
afrequency or phase modulating signal and the other an amplitude
modulating signal. This Low Frequency (LF) Generator option can
only be ordered in combination with either FM/ΦM or AM options,
12 and 14 respectively.
Waveforms: Sinusoid, square-wave, triangle, positive ramp,
negative ramp, Gaussian noise, uniform noise. (Check Option 10
for User-Defined)
Rate:
0.1 Hz to 1 MHz sinusoidal
0.1 Hz to 100 kHz square-wave, triangle, ramps
Resolution: 0.1 Hz
Accuracy: Same as instrument timebase
Output: Two BNC connectors on the rear panel, FM/ΦM OUT and
AM OUT
External Input: Rear-panel BNC. For internal modulation, add Pulse
Generator Option 24.
Drive Level: TTL compatible input
Input Logic: Positive-true or negative-true, selectable from
modulation menu.
Pulse Generator (Option 24)
Modes: Free-run, triggered, gated, delayed, singlet, doublet, triplet,
quadruplet.
Accuracy: 10 ns (5 ns typical)
Inputs/Outputs: Video pulse and sync out, rear-panel
BNC connectors
Pulse Generator option is not available without Pulse Modulation
