Frequently Asked Questions
What Makes Keysight Signal Generators Different From Others?
Keysight’s signal generators are engineered for precision-critical applications:
- Built-in vector modulation and ARB waveform capabilities
- Frequency ranges up to 44 GHz and clean signal purity
- Verified OEM calibration, latest firmware, and real specs
Designed to meet industry test standards — not just spec sheets.
Can I Trade In Older Test Equipment Toward a Purchase?
Yes — trade-in programs are available for eligible gear:
- Receive credit toward your next signal generator
- Upgrade to higher frequency or bandwidth models
- Streamline asset lifecycle and procurement processes
Contact us to evaluate your existing equipment.
What If My Signal Generator Needs Repair — Who Handles That?
KeysightCare covers eligible units:
- 10-day turnaround (Premium Used)
- 4-hour response SLA for urgent support
- All diagnostics and calibration done with OEM tools
Support is provided by Keysight service centers directly.
Is the Output Power Customizable Across All Models Above?
Yes — all models (N5182B, N5172B, M9384B, E8267D) offer output power adjustment:
- Ranges typically from –120 dBm to +24 dBm
- Precise power tuning via front panel or SCPI commands
- Ideal for testing sensitive or robust DUTs
Refer to model datasheets for specific output specs.
What Is Vector Modulation in Signal Generators?
Vector modulation enables I/Q-based signal creation:
- Supports advanced standards like QAM, OFDM, PSK
- Reproduces real-world signal impairments for DUT stress testing
- Required for 5G, radar, satcom, and GNSS simulation
All featured Keysight models (N5182B, N5172B, M9384B, E8267D) support vector modulation.
What Is the Difference Between a Signal Generator and a Function Generator?
Function generators provide basic low-frequency signals. Signal generators offer high-frequency, modulated RF signals:
- Up to 44 GHz frequency range
- Support for ARB waveforms and digital modulation
- Suited for RF validation and advanced protocol testing
They serve very different test roles.
What Is the Difference Between a Signal Generator and an Oscilloscope?
Oscilloscopes measure, signal generators stimulate:
- Scopes analyze incoming waveforms
- Signal generators output precise signals for DUTs
- Used together for validation, debugging, and compliance testing
Both are essential in a complete test environment.
