OPTION 008 RF PROFILES AND COMPLEX SWEEP
Annex-B-2
Performance data
General description
Option 008 software provides additional sweep, RF offset and RF level profiling facilities to
support the use of 2050T series Signal Generators with external amplifiers and attenuators. The
RF output from the external device can be calibrated and displayed on the front panel of the signal
generator using the RF offset and RF profile facilities.
The following specification is in addition to the specification for the 2050T series Signal
Generators.
RF offsets
The displayed signal generator output level can be offset by +80 dB
to -40 dB (in 0.1 dB steps) from the actual RF output level. Up to
5 offset values may be defined and selected in turn.
RF offsets can be enabled and disabled and their value and status
stored in non-volatile memory. RF offsets may be used in normal
signal generator modes or combined with the segmented sweep
facility.
RF profile
The actual RF output level can be adjusted by ±40 dB from its
nominal value without changing the displayed level. Up to 10
profiles may be defined and selected in turn. RF profiles can be
enabled and disabled and all RF profile information can be stored in
non-volatile memory.
Profile values can be entered at up to 100 carrier frequencies.
The RF output level is linearly interpolated between profile points.
RF profiles may be used in normal signal generator modes or
combined with the segmented sweep facility to produce complex
sweeps.
Segmented sweep
Carrier frequency sweeps can be generated which contain defined
segments each of which can have a different step size, start and
stop frequency, step time and RF level.
Start and stop
Start and stop frequency for each segment can be freely defined
within the frequency capability of the signal generator.
Step size
Minimum step size is 0.1 Hz.
Maximum step size is determined by the frequency capability of the
signal generator.
Number of steps for a particular segment is implied by the step size
and the start and stop frequencies.
Step time
20 ms to 20 s per step.
RF level
The RF level for each segment can be freely defined within the
output level capability of the signal generator.
Segments
Up to 10 segments may be defined and freely combined in any
order to produce a segmented sweep. Segmented sweeps can be
stored in non-volatile memory by using the sweep stores (0 to 19).
Modulation waveforms
Sine, triangle or square wave modulation is available to provide
amplitude, phase or frequency modulation.
