The Keysight/Agilent/HP 53132-60003 is an optional 3 GHz frequency measurement board that expands the capabilities of compatible universal and RF counters. This internal hardware option adds a third independent measurement channel to 53131A, 53132A, and 53181A series instruments, enabling precise frequency and time interval measurements up to 3 GHz. The board installs directly into the host counter’s mainframe and draws power from the instrument’s internal supply.
## Technical Specifications
• **Frequency Range:** Up to 3 GHz
• **Input Connector:** BNC (3 GHz input)
• **Input Impedance:** 50 Ω
• **Input Coupling:** AC coupled
• **Sensitivity:** −21 dBm to +13 dBm (100 MHz to 3 GHz)
• **Maximum Input Level:** 5 Vrms
• **Power Supply:** Draws from host counter internal supply (+5 V, +12 V, −9 V, −12 V rails available)
## Key Features
• Adds third independent measurement channel to compatible counter platforms
• Extends frequency measurement range beyond base 225 MHz bandwidth of primary channels
• Supports frequency, period, ratio, time interval, pulse width, rise/fall time, phase angle, duty cycle, totalize, and peak voltage measurements
• Internal PCB assembly—no external interfaces required beyond signal input connector
## Typical Applications
• RF and microwave frequency measurements to 3 GHz
• Multi-channel frequency and timing characterization
• High-frequency component and circuit testing
• Simultaneous measurement across multiple signal paths
## Compatibility & Integration
Designed for integration with Keysight/Agilent/HP 53131A, 53132A, and 53181A series universal and RF counters. Typically designated as Option 030 when configured as part of a complete counter system. Installation is internal; no user-accessible external interfaces beyond the BNC input connector.
