Sweep characteristics
12
Type
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
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

Marker
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

Channel-to-channel skew (typ)
Crosstalk (typ) < –85 dB
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.
