Modulation, burst, and sweep characteristics, continued
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.
Direction Up (start < stop) or Down (start > stop)
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, 1-ms resolution
hold time 0 to 3600 s, 1-ms resolution
Return time 0 to 3600 s, 1-ms resolution
trigger source 14 Immediate (continuous), external (rear-panel connector), manual (front-panel button), bus, or Internal timer
Marker Indicated by the trailing edge of the Sync pulse; adjustable to any frequency between Start and Stop for
Linear and Logarithmic types or any frequency in the list for List type.
Internal timer for FSK, BPSK, burst, and sweep
Range 1 µs to 4000 s, 4-ns resolution
Standard
Operating modes Independent, Coupled parameter(s), Combined (Ch 1 + Ch 2), equal (Ch 1 = Ch 2),
or Differential (Ch 1 = −Ch 2)
Parameter coupling None, Frequency (ratio or difference) and/or amplitude and DC offset
Relative Phase 0° to 360°, 0.1° resolution
Channel-to-channel skew (typ) < 100 ps (both channels configured identically)
Crosstalk (typ) < –85 dB
IQ Player (Option IQP)
Operation this option enables a two-channel model with arbitrary waveform capability to function as a baseband
IQ (quadrature modulation) source. Programmable impairments include amplitude imbalance, DC offset
difference, and channel-to-channel time skew.
