Amplitude Modulation
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.
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, front or rear-panel
BNC, 50 Ω or 600 Ω input impedance. All options selectable from
modulation menu.
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
Internal AM Generator:
Waveforms: Sinusoid, squarewave, triangle, positive ramp,
negative ramp, Gaussian noise, uniform noise, user-defined➃
Rate: 0.1 Hz to 1 MHz sinusoidal
0.1 Hz to 100 kHz squarewave, triangle, ramps
Resolution: 0.1 Hz
Accuracy: Same as instrument timebase
Output: BNC connector, rear panel
Frequency Modulation
Maximum FM Deviation:
Locked Mode (1 kHz to 8 MHz rates): The lesser of ±10 MHz or
rate x 300
Locked Low Noise Mode (50 kHz to 8 MHz rates): The lesser of
±10 MHz or rate x 3
Unlocked Narrow Mode (DC to 8 MHz rates): ±10 MHz
Unlocked Wide Mode (DC to 100 Hz rates): ±100 MHz
FM Bandwidth (3 dB):
Locked Mode: 1 kHz to 10 MHz
Locked Low Noise Mode: 30 kHz to 10 MHz
Unlocked Narrow Mode: DC to 10 MHz
Unlocked Wide Mode: DC to 100 Hz
Flatness (locked mode 10 kHz to 1 MHz rates):

±1 dB
Accuracy (100 kHz rate): ➄
10% (5% typical)
Incidental AM (± 1 MHz deviation, 1 MHz rate): < 2%
Harmonic Distortion (±1 MHz deviation, 10 kHz rate): <1%
External FM Input: Front or rear panel BNC, 50 Ω or 600 Ω input
impedance. All options selectable from modulation menu.
FM Sensitivity: Continuously variable from ±10 kHz per volt to
±20 MHz per volt (Locked, Locked Low Noise and Unlocked
Narrow FM modes), or ±100 kHz per volt to ±100 MHz per volt
(Unlocked Wide FM mode), selectable from modulation menu.
Maximum Input: ± 1V
Internal FM Generator:
Waveforms: Sinusoid, squarewave, triangle, positive ramp,
negative ramp, Gaussain noise, uniform noise, user-defined

Output: BNC connector, rear panel
Phase Modulation (FM, Option 6)
ΦM Deviation:
Narrow Mode (DC to 8 MHz Rates): The lesser of ±3 radians
or ±5 MHz/rate
Wide Mode (DC to 1 MHz Rates): The lesser of ±400 radians
or ±10 MHz/rate.
ΦM Bandwidth (3 dB, relative to 100 kHz rate):
Narrow Mode: DC to 10 MHz
Wide Mode: DC to 1 MHz
ΦM Flatness (relative to 100 kHz rate):
Narrow Mode (DC to 1 MHz rates): ±1 dB
Wide Mode (DC to 500 kHz rates): ±1 dB
ΦM Accuracy (at 100 kHz sine wave): 10% ➄
External ΦM Input
: Front or rear panel BNC (shares the
FM input), 50 Ω or 600 Ω input impedance. All options selectable
from modulation menu. Shares connectors with FM.
ΦM Sensitivity: Continuously variable from ±0.0025 radians per
volt to ±5.0 radians per volt (Narrow ΦM mode) or ±0.25
radians per volt to ± 500.0 radians per volt (Wide ΦM mode),
selectable from modulation menu.
