The Tektronix VX4730 is a 1-slot, C-size VXI module delivering high-power, 12-channel Digital-to-Analog conversion in a single integrated package. Each channel operates as an independent, individually programmable DAC with 16-bit resolution and ±16.3835 V output capability. The module drives up to 60 mA per channel with all channels active, or delivers full ±16.3835 V into 40 Ω loads on individual channels, subject to a 720 mA aggregate current limit across all 12 channels.

– Compatibility & Integration
The VX4730 installs directly into any approved VXIbus system and conforms to VXI mechanical and electrical standards. Annual calibration adjustment is required to maintain published specifications; adjustment should be performed at the module’s operating temperature. Service operations are restricted to qualified personnel.
