BURST
[4]
Type Counted or Gated
Count 1 to 100,000,000 cycles, or infinite
Gated Produces complete cycles while
Ext Trig is asserted
Start/Stop Phase -360° to 360°, 0.1° resolution
Trigger Source Internal Timer or Ext Trig connector
Marker Adjustable to any cycle; indicated
by the trailing edge of the Sync
pulse
SWEEP
[2]
Type Linear, Logarithmic, 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 linearly from Stop to Start).
Direction Up (Start freq < Stop freq) or Down
(Start freq > Stop freq)
Start & Stop
Frequencies
Any frequency within the
waveform's range.
Sweep Time
(except IMM
trigger mode)
Linear:
1 ms to 3600 s, 1 ms resolution;
3601 s to 250,000 s, 1 s resolution
Sweep Time for
IMM trigger
Linear:
1 ms to 3600 s, 1 ms resolution;
3601 s to 8,000 s, 1 s resolution
Sweep Time Logarithmic: 1 ms to 500 s
Hold Time 0 s to 3600 s, 1 ms resolution
Return Time 0 s to 3600 s, 1 ms resolution
Trigger Source Immediate (continuous), External,
Single, Bus, or Timer
Marker
Adjustable to any frequency between Start and Stop
for Linear and Logarithmic types or any frequency in
the list for List type; indicated by the trailing edge of
the Sync pulse
INTERNAL TIMER FOR FSK, BPSK, BURST, AND
SWEEP
Range 1 µs to 8,000 s, 6-digit or 4-ns
resolution
2-CHANNEL CHARACTERISTICS (33522A ONLY)

• Equal (Ch2 = Ch1)
• Differential (Ch2 = -Ch1)
Parameter
Coupling
• None
• Frequency (Ratio or Difference)
• Amplitude & DC Offset
Relative Phase 0 degrees to 360 degrees, 0.1

[1] Subject to maximum output voltage limits.
[2] All frequency changes are phase-continuous.
[3] Subject to pulse width limits.
[4] The maximum Sine-wave frequency for counted
and gated burst is 10 MHz unless Burst Count is
set to "Infinite". Counted Burst operation is not
allowed for Gaussian Noise.
