Description
Passive parts are easy to measure. Amplifiers, mixers and converters are not, because they change the signal. The Keysight E5081A network analyzer is an ENA-X vector network analyzer built for that harder job. Lost in HCM lists it for rental and sale, so you can book one for a project or request a purchase quote.
E5081A configuration summary
| Frequency range | 10 MHz to 20 or 44 GHz, configuration dependent |
|---|---|
| Built-in test ports | 2 or 4 |
| Maximum sources | 2 |
| Integrated low-noise receivers | 2 |
| Measurement scope | S-parameters, noise figure, mixer and optional modulation distortion |
| Test set | Configurable, with direct receiver access on selected options |
Active devices need more than S-parameters
A power amplifier has gain, compression and noise to check, not just reflection. The ENA-X packs those tasks into one platform, so you reconnect less and add fewer error sources at the device plane. For example, one setup can run S-parameters first and noise figure afterward. As a result, you move less hardware between tests.
Where the Keysight E5081A network analyzer fits
- Power-amplifier characterization
- 5G and satellite component development
- Noise-figure and gain measurements
- Mixer and frequency-converter testing
- Temporary RF lab capacity for one project
Modulation distortion, such as EVM, needs an optional workflow, so name it in your request. Direct receiver access on selected options also lets you build high-power setups with external parts.
Choosing ports and frequency
The frequency range depends on the configuration. It reaches 20 GHz on some units and 44 GHz on others. Likewise, the port count is 2 or 4. Therefore, list the highest frequency and the number of device ports before you ask for a quote. Also add the calibration standards and connector type.
Rent or buy the Keysight E5081A network analyzer
An RF design sprint or a customer qualification may need a VNA for a few weeks. That suits a rental. A team that measures active parts daily may prefer to own one. In both cases, Lost in HCM supplies the analyzer and gives the quote, while SMK Vietnam only shows the listing.
Quote checklist
Give Lost in HCM the options, accessories, delivery site and period you need. Then request a quote from Lost in HCM. For similar instruments, open the network analyzer listings. Keysight keeps the official ENA-X documentation on its website, and you can contact SMK Vietnam with listing questions.
E5081A questions
Does every unit reach 44 GHz?
No. The range is 10 MHz to either 20 or 44 GHz, depending on the configuration.
Can it measure noise figure?
Yes, noise figure sits in its measurement scope. Confirm the installed options for your test.
Is EVM testing included?
Modulation distortion is optional, so ask for it when you request the quote.
