The HP 70004A is a color graphics display unit designed for integration with HP 70000 Series modular measurement systems. It provides the primary human interface and real-time visualization platform for spectrum analysis and system configuration data across multiple modular instruments. Unit has been tested and confirmed fully operational.
Technical Specifications
The display features 1024 × 400 pixel resolution with 16 simultaneous colors selected from a 4096-color palette. RGB video output operates at non-standard resolution with sync on green, 25 kHz horizontal scan frequency, and 60 Hz vertical sweep rate. The unit accommodates 1/8-, 1/4-, 3/8-, and 1/2-width modules within the mainframe section, supporting a maximum of four 1/8-width modules. Power supply operates from 115–230 V, 50/60/400 Hz at 350 VA maximum, supplied by the mainframe. Operating temperature range is 0 to +55 °C; storage range extends from −40 to +75 °C. The unit maintains 0 to 95% relative humidity at +55 °C and meets MIL-T-28800E Type III Class 3 vibration and shock specifications, with EMC compliance to MIL-STD 461 B and CISPR pub 11.
Physical dimensions are 222.0 mm (H) × 425.4 mm (W) × 526.0 mm (L). Cooling and power management are provided by the mainframe assembly.
– Key Features
• High-resolution color display with 1024 × 400 pixel matrix
• Modular System Interface Bus (MSIB) digital communication for instrument control
• HP-IB remote programming and operation capability
• HP-IB printer/plotter graphics output; native support for HP PaintJet full-color printing
• Front-panel HP-HIL connector for keyboard, mouse, or trackball input
