The Keysight/Agilent/HP 53131-60002 is a replacement front panel display board assembly for the 53131A and 53132A universal counters. This component restores visual output integrity and ensures accurate display of critical measurement parameters including frequency, period, time interval, pulse width, rise/fall time, phase angle, duty cycle, and peak voltage. The display board is essential for maintaining full operational capability of these instruments.
## Technical Specifications
The 53131-60002 interfaces directly with the main logic board of compatible counters. Original equipment uses a Vacuum Fluorescent Display (VFD) technology. The board requires multiple supply voltages including +5V, +12V, -9V, and -12V, depending on the specific counter model and options.
## Key Features
• Direct replacement assembly for front panel display subsystem
• Compatible with both two-channel and three-channel configurations
• Supports full measurement capability of host instrument
• VFD display technology for enhanced readability
• Standard interface with main logic and power distribution circuits
## Instrument Specifications
The Keysight 53131A delivers 10 digits/second frequency/period resolution and 500 ps time interval resolution across a two-channel 225 MHz baseband. Optional third channels extend frequency measurement to 3 GHz, 5 GHz, or 12.4 GHz.
The HP 53132A provides enhanced performance with 12 digits/second frequency/period resolution and 150 ps time interval resolution. It includes advanced arming modes for time interval measurements, typically configured with two 225 MHz channels and an optional third channel rated to 12.4 GHz.
## Compatibility & Integration
This replacement board is engineered for direct substitution in:
• Keysight 53131A Universal Counter
• Agilent 53131A Universal Counter
• HP 53132A Universal Counter
Both host instruments support GPIB (IEEE-488) and RS-232 interfaces for remote control and data transfer, maintaining full integration with existing test systems and measurement workflows.
