UNI-T USG3000M-PM Pulse Modulation Option

Overview

The USG3000M-PM is a premium pulse modulation option for the USG3000M series RF signal generators. This option enhances your USG3000M generator with comprehensive pulse modulation capabilities, enabling the creation of precisely controlled pulsed RF signals essential for radar system development, wireless communications testing, and electronic warfare applications.

Key Features

• High On-Off Ratio: Achieves up to 80 dB on-off ratio for clean, well-defined pulse generation
• Fast Transition Time: Rising/falling times of less than 20 ns (typical) for accurate edge definition
• Multiple Pulse Modes: Includes free-run, square, externally triggered, adjustable doublet, gated, and pulse train modes
• Customizable Pulse Trains: Create complex sequences of pulses with varying widths and delays
• Flexible Configuration: Use internal or external pulse sources for maximum versatility

Technical Specifications

Application Examples

Radar System Development

Simulate radar transmitter pulses with precise timing and amplitude control. The USG3000M-PM allows engineers to:

• Generate pulse repetition intervals (PRIs) for different radar modes
• Test radar receiver sensitivity with controlled pulse widths and amplitudes
• Verify radar signal processing algorithms with customized pulse patterns
• Simulate complex radar environments for system validation

Wireless Communications Testing

Evaluate pulsed communication systems with accurate pulse modulation:

• Test time division multiplexing (TDM) systems
• Characterize transmitter and receiver performance under pulsed conditions
• Verify system behavior during pulsed interference conditions
• Evaluate power amplifier performance during pulsed operation

Electronic Component Characterization

Characterize RF components under pulsed conditions:

• Measure amplifier gain compression during pulsed operation
• Test filter response to pulsed signals
• Evaluate thermal effects in components using pulsed excitation
• Characterize receiver recovery time from strong pulse signals

Integration with USG3000M Series

The USG3000M-PM option can be installed on any model in the USG3000M series, including:

• USG3045M (9 kHz to 4.5 GHz)
• USG3045M-P (9 kHz to 4.5 GHz with mechanical attenuator)
• USG3065M (9 kHz to 6.5 GHz)
• USG3065M-P (9 kHz to 6.5 GHz with mechanical attenuator)

Once installed, pulse modulation capability is seamlessly integrated into the generator's user interface, with dedicated controls for all pulse parameters. The option works in conjunction with other modulation types for maximum flexibility in signal creation.

Ordering Information

For enhanced pulse generation capabilities with even narrower pulse widths, consider adding the USG3000M-PG narrow pulse generator option as well.

Installation

The USG3000M-PM option can be installed at the time of purchase or added later as an upgrade. For existing units, the option is enabled through a license file installation procedure that can be performed by the user.
