Switching frequency band
2658 consists of the following three bands.
Frequency band
Base band
Band 1 -
Band 1 +
Measured frequency range
50kHz to 3.5GHz
3.3GHz to 6.3GHz
6.2GHz to 8.5GHz
The frequency band is selected to be the least band number, based on Center frequency and Span.
(At the span less than 200MHz, only one band is used.)
When the setting frequency range belongs to two bands, the lower band has priority.
Note: Switch frequency band allows only to automatical setting.
The frequency connection point of two bands is fixed as below table.
Two bands
Base band and band 1 -
Band 1 – and band 1 +
Frequency connection point
3.4GHz
6.2GHz
Note: The trace may fall into disorder just a little at the frequency connection point. For the precise
measurement is needed, Center frequency or Span should be set so that the measured
frequency range is in one band.
