Description
A noisy test source hides the very thing you want to measure. The Keysight E8257D signal generator is a PSG analog source with low phase noise and configurations that reach 67 GHz. Lost in HCM lists it for rental and sale, and it arranges service on request.
PSG headline figures
| Maximum frequency | 67 GHz |
|---|---|
| Minimum frequency | 100 kHz; configured ranges may begin at 250 kHz |
| Output power at 1 GHz | 21 dBm nominal headline value |
| Phase noise at 1 GHz, 20 kHz offset | -143 dBc/Hz |
| Harmonics at 1 GHz | -55 dBc |
| RF outputs | 1 |
Installed hardware, options and licenses change these values, so the quoted configuration takes precedence.
Why spectral purity matters
A receiver test needs a clean tone. If the source adds its own noise, the receiver looks worse than it is. Therefore, low phase noise supports radar and receiver measurements that depend on close-in purity. In addition, you can add AM, FM, phase and pulse modulation options when a test needs them.
Jobs for the Keysight E8257D signal generator
- Radar and electronic-warfare receiver testing
- Satellite and microwave component characterization
- ADC clock and local-oscillator stimulus
- High-power amplifier and receiver-blocking measurements
High-power options help here. A long cable or a switch matrix eats output level, so extra power at the source keeps the device under test properly driven.
Plan the options before you rent
Frequency coverage is the first choice. Output power, modulation and attenuator needs come next. However, the headline numbers do not all apply at once, so ask Lost in HCM for the exact configuration. Also check cable loss at your highest test frequency.
Rent or buy the Keysight E8257D signal generator
A single qualification run or a short receiver study suits a rental. A lab that needs a stable analog reference every week may prefer to buy. Purchase quotes can cover new, refurbished or used units. Lost in HCM supplies the generator, while SMK Vietnam only shows the listing.
