The flexible modulation sources allow for internal, external, or combined operation, adapting to diverse testing scenarios. Each modulation type features precise control of parameters, enabling accurate simulation of real-world signal conditions.

For applications requiring pulsed RF signals, the optional USG5000M-PM pulse modulation capability delivers outstanding on-off ratios up to 80 dB with fast rise/fall times below 20 ns. The pulse modulation can operate in various modes including free-running, triggered, gated, and customized pulse train patterns. When combined with the optional USG5000M-PG narrow pulse generator, the system can generate pulses as narrow as 20 ns with 10 ns resolution, perfect for radar system testing and pulse characterization applications at microwave frequencies.

The USG5014M features a stable clock source and offers optional pulse modulation and a narrow pulse generator. The USG5000M-PG option delivers a minimum pulse width of 20 ns with a resolution of 10 ns, meeting the requirements of advanced radar systems, satellite communications testing, and high-speed digital applications. The pulse generator provides exceptional timing precision and stability across multiple operating modes.

With the optional pulse modulation package, you can generate customized pulse trains with precisely controlled timing parameters. Multiple pulse modes are supported, including Free-Run, Square, External Triggered, Adjustable Doublet, External Trigger Doublet, Gated, External Pulse, and Pulse Train. The outstanding on-off ratio of ≥ 80 dB at frequencies up to 6.5 GHz (≥ 70 dBc from 6.5 GHz to 14 GHz) ensures clear signal transitions with minimal bleed-through, while fast rise/fall times below 20 ns enable accurate simulation of high-speed pulsed systems. These capabilities are essential for radar system testing, pulse characterization, and advanced communications applications at microwave frequencies.

The USG5014M features comprehensive sweep capabilities that simplify component characterization and system response testing across microwave frequencies. The instrument supports frequency, amplitude, and list sweep modes with customizable step sizes and dwell times. Engineers can perform frequency sweeps across the full 9 kHz to 14 GHz range with linear or logarithmic step patterns, enabling efficient measurement of frequency-dependent parameters like filter responses or amplifier gain flatness.

For more complex testing requirements, the list sweep mode allows creation of custom frequency-amplitude point sequences, ideal for focused testing at specific frequencies of interest. Sweep operation can be triggered via multiple methods including free-running, external trigger, manual key press, or computer command, providing flexibility for both manual testing and automated sequences. These advanced sweep functions streamline the characterization process and reduce overall test time compared to point-by-point manual measurements, particularly valuable when working with wideband components across microwave frequencies.

The USG5014M features a 5-inch capacitive multi-touch screen with an intuitive user interface that accelerates test setup and enhances productivity. The flat design with clear parameter organization allows for quick access to commonly used functions, while the logical menu structure ensures even complex operations can be performed with minimal keystrokes. The touch interface supports gestures for common operations, reducing setup time and allowing engineers to focus on test results rather than instrument configuration.

Visual feedback is provided through clear waveform displays for both output and modulating signals, enabling immediate verification of signal characteristics. The interface allows seamless switching between time-domain and frequency-domain views, providing comprehensive signal visualization. Numerical parameters are displayed with high visibility and logical grouping, ensuring settings are easily verifiable at a glance. This thoughtful interface design reduces learning curves and improves testing efficiency in both research and production environments, even when working with complex microwave signals.

The USG5014M includes a built-in 50 MHz function/arbitrary waveform generator that extends the instrument's versatility beyond RF applications. This integrated LF generator produces high-quality sine waves up to 50 MHz, square and pulse waveforms up to 15 MHz, and triangular waves up to 3 MHz. With output amplitude adjustable from 1 mVpp to 2 Vpp and DC offset control, it provides the signal flexibility needed for various testing applications without requiring additional equipment.

The function generator includes advanced capabilities such as linear and logarithmic sweep functions and comprehensive modulation options including AM, FM, and pulse modulation. For digital communications testing, it supports ASK, FSK, PSK, and QAM modulation with various digital patterns. This integration delivers significant value by combining two essential instruments in one compact unit, saving both bench space and equipment costs while maintaining signal generation quality across both baseband and microwave frequency ranges.

The USG5000M-PK power meter option transforms the USG5014M into a comprehensive RF test solution by adding accurate power measurement capabilities. Connected through the front panel USB port, this accessory enables precise RF power measurements, particularly valuable for calibrating output power levels and verifying signal integrity at the device under test. The power measurement system allows direct verification of actual received power, eliminating uncertainty in test setups at microwave frequencies.

A key capability of the power meter option is the line loss calibration function, which automatically compensates for cable and fixture losses in the test path. This ensures that the power level reaching the device under test matches the specified value, improving measurement accuracy and test consistency. This feature is especially valuable when working at higher microwave frequencies where cable and connector losses become increasingly significant. By combining signal generation and power measurement in a single coordinated system, the power meter option streamlines test procedures and reduces the need for additional test equipment.
