What are the baseband bandwidth upgrade details regarding options B25, S40, SU1 and BBA?
Definitions of Options: N9020A-xxx are options ordered at the time of initial instrument purchase. N9020AK-xxx are options ordered as post sale upgrades.
- N9020A or N9020AK-BBA, Baseband Analog I/Q Inputs
- N9020A or N9020AK-B25, Analysis BW, 25 MHz
- N9020A-S40, Baseband I/Q Analysis BW, 40 MHz
- N9020AK-S40; Upgrades Baseband BW from 10 to 40 MHz
- N9020A-SU1, Not allowed at time of initial purchase
- N9020AK-SU1, Upgrades Baseband BW from 25 to 40 MHz (Requires B25 in the instrument before upgrading)
The table below identifies all possible BW upgrade combinations from the original instrument configuration.

1SU1 identifies as S40 in the analyzer.
2 Zoom mode only. Baseband 2 channel measurements limited to 20 MHz.
If you want to make a 2-channel measurement with the 89600 VSA software in vector mode, 40 MHz is the maximum bandwidth you can achieve per channel. This means that two simultaneious IF streams at 10.7 MHz or 21.4 MHz for example could be monitored and compared to each other in 89601A vector mode in time and frequency domains.
