Measurement Setup Parameters
Model Option
Maximum Span (Analysis Bandwidth)
-SR1 -F05
390.625MHz (650 MHz in interleaved mode)
-SR1 -F10
390.625MHz (781.25 MHz in interleaved mode)
-SR2 -F05
625 MHz (650 MHz in interleaved mode)
-SR2 -F10
625 MHz (1.25 GHz in interleaved mode)
The maximum span is obtained with following formula:
Maximum Span = Min( Sample Rate / 2.56 ; Analog Bandwidth)
The analog bandwidth depends on the digitizer, the option (-Fxx) and interleaving
mode (see product datasheet for details).
Maximum span depends also on the digitizer sampling rate.

.
For digitizer with -DDC option, by default, the down-conversion is
done by the hardware when span: < 320 MHz (-SR2) or for span <
180 MHz (-SR1).
If the specified frequency differs from the instantaneous analysis
bandwidth (IBW) supported by the hardware digital down-
converter, the down-conversion is done by the hardware at the
closest highest IBW and remaining processing is managed by VSA
(Please refer to your digitizer user manual or datasheet for the list
of IBW supported by the hardware).
For digitizer with -LDC option, by default, the down-conversion is
done by the hardware when span: < 80 MHz (-SR2) or for span <
50 MHz (-SR1).
If the specified frequency differs from the instantaneous analysis
bandwidth (IBW) supported by the hardware digital down-
converter, the down-conversion is done by the hardware at the
closest highest IBW and remaining processing is managed by VSA
(Please refer to your digitizer user manual or datasheet for the list
of IBW supported by the hardware).
ResBW:Standard VSA parameter. Can be configured by user.
Main Time Length: Standard VSA parameter. Can be configured by user.
Maximum value depends on the memory option of your module.
