Modulation, burst, and sweep characteristics
Amplitude modulation (AM)
Source Internal or external (all models), or other channel (all 2-channel models)
Type Full-Carrier or Double-Sideband Suppressed-Carrier (DSSC)
Depth
3,11
0% to 120%, 0.01% resolution
Frequency modulation (FM)
12
Source Internal or external (all models), or other channel (all 2-channel models)
Deviation 1 µHz to 15 MHz, 1-µHz resolution (all 33500 Series models)
1 µHz to 40 MHz, 1-µHz resolution (33611A/33612A)
1 µHz to 60 MHz, 1-µHz resolution (33621A/33622A)
Phase modulation (PM)
Source Internal or external (all models), or other channel (all 2-channel models)
Deviation 0º to 360º, 0.1º resolution
Frequency-shift key modulation (FSK)
12
Source Internal timer or rear-panel connector
Mark & space Any frequency within the carrier signal’s range
Rate ≤ 1 MHz
Binary phase-shift key modulation (BPSK)
Source Internal timer or rear-panel connector
Phase shift 0º to 360º, 0.1º resolution
Rate ≤ 1 MHz
Pulse width modulation (PWM)
Source Internal or external (all models), or other channel (all 2-channel models)
Deviation
6
0% to 100% of pulse width, 0.01% resolution
Additive modulation (Sum)
Source Internal or external (all models), or other channel (all 2-channel models)
Ratio
11
0% to 100% of carrier amplitude, 0.01% resolution
Burst characteristics
10
Type Counted or gated
Counted burst operation Each trigger event causes the instrument to produce from 1 to 10
8
or an “infinite” number of waveform cycles
Gated burst operation Instrument produces waveforms while the trigger is in the “on” state. For Gaussian Noise, waveform generation stops
immediately when the trigger is in the “off” state. All other waveforms stop at the completion of a cycle; more than one cycle
might elapse before generation stops.
Start/stop phase
19
-360° to +360°, 0.1° resolution
Trigger source Internal timer or rear-panel connector
Marker Indicated by the trailing edge of the Sync pulse; adjustable to any cycle of the burst
Sweep characteristics
12
Type Linear, Logarithmic, or List (up to 128 user-defined frequencies)
Operation Linear and Logarithmic sweeps are characterized by a Sweep time (during which the frequency changes smoothly from Start
to Stop), a Hold time (during which the frequency stays at the Stop frequency), and a Return time (during which the frequency
changes smoothly from Stop to Start). Returns are always linear in the 33600A Series.
Direction Up (start freq < stop freq) or Down (start freq > stop freq)
