I. Core Technical Parameters
1. Frequency Coverage and Accuracy
The N5172B offers two frequency options:
N5172B-503: 9 kHz to 3 GHz
N5172B-506: 9 kHz to 6 GHz
With frequency resolution up to 0.001 Hz and supporting 0.1° phase offset adjustment, it meets the stringent frequency accuracy requirements in communication equipment R&D. For example, in 5G base station testing, it can accurately simulate RF signals in the 3.5 GHz band to verify the frequency response characteristics of the receiver.
2. Power Output and Dynamic Range
At a typical operating frequency of 1 GHz, the output power range is **-144 dBm to +26 dBm**, and it is equipped with a 130 dB electronic attenuator (5 dB step). This wide dynamic range design can meet:
Weak signal testing: For example, when verifying the sensitivity of the RF front end, a -144 dBm level signal can be output to simulate low-level interference in a real environment.
High-power drive: The +26 dBm output capability can directly drive a power amplifier to test its saturation characteristics and linearity.
3. Phase Noise and Spurious Suppression
At a 1 GHz carrier frequency and 20 kHz offset, the single-sideband phase noise is as low as **-122 dBc/Hz**, and with -72 dBc non-harmonic suppression capability, it can effectively ensure:
Radar system testing: Low phase noise ensures high resolution of echo signals and avoids target misjudgment.
Communication receiver testing: Spurious suppression characteristics can simulate signal interference in complex electromagnetic environments to verify the equipment's anti-interference capability.
4. RF Modulation Bandwidth and Waveform Generation
Supports RF modulation bandwidth from 120 MHz to 200 MHz (depending on the option), and can generate complex modulated signals such as LTE, WLAN, and GNSS. Built-in 512 Msample waveform memory supports real-time I/Q signal generation and arbitrary waveform playback. For example, in 5G NR testing, predefined 5G waveform files can be directly loaded for rapid signal simulation.
5. Modulation Functions and Speed
Supports AM/FM/PM analog modulation and narrow pulse modulation (option UNW), with specific indicators including:
AM modulation: Depth 0-100%, rate 0-50 kHz
FM modulation: Rate up to DC to 7 MHz at 100 kHz frequency deviation
Pulse modulation: Pulse width can be as low as nanoseconds, rise/fall time ≤3 ns
Frequency switching speed ≤800 μs, combined with 1024 commonly used frequency cache functions, can significantly improve production line testing efficiency. For example, in the batch testing of mobile phone RF modules, it quickly switches signals in different frequency bands, reducing downtime.
II. Key Technical Characteristics
1. Vector Modulation Capability
As a vector signal generator, the N5172B supports digital modulation methods such as ASK, FSK, MSK, PSK, and QAM, and provides custom I/Q modulation functions. In WLAN testing, it can generate 256-QAM signals according to the 802.11ac standard to verify the error vector magnitude (EVM) performance of the receiver, with an EVM indicator as low as 0.4% (80 MHz bandwidth).
2. Hardware Architecture Optimization
It adopts a high-stability oscillator and low-noise amplifier design to ensure signal purity and long-term stability. The internally integrated multi-function generator (option 303) can generate basic waveforms such as sine waves and square waves to meet basic testing needs. It also supports differential I/Q output (option 1EL), suitable for MIMO system testing.
3. Software Ecosystem Support
Compatible with Keysight PathWave Signal Studio software, it can quickly generate complex modulated signals such as LTE, GNSS, and DVB. For example, in satellite communication testing, predefined waveforms are loaded into the device via software to generate RF signals that meet the standard, greatly shortening the test preparation time. In addition, it supports MATLAB control and SCPI programming, making it easy for users to customize automated test processes.
4. Flexible Interfaces and Expandability
Provides multiple communication interfaces such as 1000BaseT LAN, USB 2.0, and GPIB, supports the LXI standard protocol, and can be seamlessly integrated into automated test systems. For example, in automotive electronics production lines, multiple devices can work together through the LAN interface to complete batch testing of in-vehicle radar modules.
III. Typical Application Scenarios
1. Communication Equipment R&D and Manufacturing
5G base station testing: Simulate 5G NR signals in the 3.5 GHz band to test the sensitivity and bit error rate of the base station receiver.
Mobile phone RF module verification: Use the fast frequency switching function to perform multi-band frequency sweep testing and detect the frequency response consistency of the device.
Wi-Fi 6/6E testing: Generate OFDMA signals according to the 802.11ax standard to evaluate the throughput and anti-interference capability of the wireless network card.
2. RF Component Testing
Filter characteristic analysis: Output signals of specific frequency and power to test insertion loss, out-of-band suppression, and other parameters.
Power amplifier verification: Use high output power characteristics to test the linearity and saturation power of the amplifier, and evaluate the phase noise transfer characteristics with low phase noise characteristics.
3. Aerospace and Defense
