Speciications (continued)
Modulation, burst, and sweep characteristics, continued
Sweep characteristics¹²
Type
Linear, Logarithmic, or List (up to 128 user-deined 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
Marker
Immediate (continuous), external (rear-panel connector), manual (front-panel button), bus, or Internal timer
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
Two-channel characteristics (33612A/22A only)
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 conigured identically)
Crosstalk (typ)
IQ Player (Option IQP)
< –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.
Channel-to-channel amplitude −30% to +30%, 0.001% resolution
imbalance ¹¹
Channel-to-channel
± (5 VDC - Peak AC), 0.1-mV resolution into 50 Ω
DC offset difference
± (10 VDC - Peak AC), 0.2-resolution into open circuit
Channel-to-channel
