Description
Power-supply engineers rarely think of network analyzers, yet loop gain is a frequency-response problem. The Keysight E5061B network analyzer starts as low as 5 Hz and reaches 3 GHz, so one instrument covers audio-range control loops and RF parts. It has two built-in ports. Lost in HCM lists it for rental and sale in Vietnam.
From control loops to RF
This ENA can begin as low as 5 Hz, depending on the configuration. As a result, it supports DC-DC converter loop-gain measurements as well as filters, amplifiers and passive components. Time-domain and gain-phase options add cable and power-integrity troubleshooting. A loop-gain test compares signals on both sides of the feedback path, so ask for the gain-phase option if that is your goal.
Keysight E5061B network analyzer summary
| Item | Listed value |
|---|---|
| Maximum frequency | 3 GHz |
| Minimum frequency | 5 Hz, depending on configuration |
| Built-in ports | 2 |
| System impedance | 50 or 75 ohm |
| Sources | 1 |
| Optional capability | Impedance analysis and DC bias |
The installed test set sets the exact range. So confirm the configuration before you plan a sweep.
Choose the test set first
The 50 ohm and 75 ohm versions are different configurations. Pick the one that matches your parts and cables. Then ask which calibration kit, cables and fixtures come with the unit. Impedance analysis also needs the right LF-RF configuration and fixtures, so mention it if you measure components.
Common measurements
- Transmission and reflection checks on filters and amplifiers
- S-parameter measurements on RF parts
- Cable and fixture fault location
- Production verification and teaching in RF labs
For jobs outside this list, ask Lost in HCM whether another analyzer would suit the work better.
Request the Keysight E5061B network analyzer
Rental suits a project or a course, while purchase suits a station that runs daily. Send the frequency range, impedance, options and dates. Availability, accessories and calibration documents are confirmed for each quotation, and then request a quote from Lost in HCM. You can also compare other network analyzers, visit Keysight or contact SMK Vietnam.
E5061B questions
How many ports does it have?
It provides two built-in test ports.
Can it measure impedance?
Yes, with the right LF-RF and impedance-analysis configuration and fixtures.
What should I confirm before renting?
Confirm the frequency range, the 50 or 75 ohm test set, options, calibration kit, cables and fixtures.
