The 3488A and the 3499A are legacy models. For new designs see the Keysight DAQ970A Series or the Keysight 34980A Series.
The 3488A has been replaced by the 3499 Switch Family. The 3499A/B/C are software and firmware compatible with the 3488A, while adding a selection of 20 additional switch modules.
The Keysight 3488A provides signal switching with the integrity and isolation needed for high-performance production test systems. It also offers a flexible, low-cost interconnection for automating experiments on the bench and for developing tests in the lab. The Keysight 3488A is designed to hold up to five of the following switch and control modules:
- 10-channel relay multiplexer (opt 010)
- 10-channel general purpose relay (opt 011)
- Dual 4-channel VHF switch (opt 012)
- 4 x 4 matrix switch (opt 013)
- 16-bit digital input/output (opt 014)
- Breadboard (opt 015)
- 3-channel 18 GHz switch (opt 016)
- 7-channel form-C relay (opt 017)
- 2-channel microwave switch (opt 018)
- 1.3 GHz 50 and 75 ohm multiplexer (opt 019, opt 020)
- DC to 26.5 GHz signal switching
- Up to 50 channels
- Matrix, multiplexer, and general purpose relays
- 40 configuration storage registers
- Digital I/O control and actuation
- 11 switch and control modules
