7
Burst 9
Type Counted or gated
Count 1 to 1x10 8 cycles, or infinite
Gated Produces complete cycles while Ext Trig is asserted
Start/stop phase 4 -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 7
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 smoothly from Stop to Start). Returns are always linear.
Direction Up (Start freq < Stop freq) or Down (Start freq > Stop freq)
Start and stop frequencies Any frequency within the waveform's range
Sweep time Linear: 1 ms to 3600 s, 1 ms resolution;
3601 s to 250,000 s, 1 s resolution
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 10 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 8000s, 6-digit or 4 ns resolution
2-channel characteristics (33522A only)
Operating modes Independent, coupled parameter(s), combined (Ch 1 + Ch 2),
Equal (Ch 2 = Ch 1), or differential (Ch 2 = -Ch 1)
Parameter coupling None, frequency (ratio or difference) and/or amplitude and DC offset
Relative phase 0° to 360°, 0.1° resolution
Skew (typ) < 200 ps (when performing identical operations)
Crosstalk (typ) < -85 dB
