Hameg HO732

The HO732 is a communication interface for Rohde&Schwarz test and measurement equipment. It provides both Ethernet (RJ-45) and USB 2.0 (device, B) connections. The vendor states that the interface can be used with scope/generator/source models in the HM, HMF, HMO, HMP, and HMS series.

Hardware

  • ST STM32F407ZGT6 (MCU)
  • Altera EPM570F100C5N (programmable logic)
  • Micrel KSZ8721BL (Ethernet PHY)
  • SMSC USB3320C (USB PHY)
  • (only optionally populated?) CY7C1041DV (local memory?)
  • TI LC02A (7402 quad NOR gates? chip select logic? backplane glue?)

The USB interface can be configured to either CDC or TMC.
