HamGeek 50KHz-1.5GHz Vector Network Analyzer NanoVNA Vector w/ 4" LCD Display For UHF Antenna NanoVNA-H4

Features:
- With DC dimming method, 4" full-view LCD screen can be seen more clearly for outdoor uses, and more comfortable for indoor uses
- Optimized Electric Bridge: Making full use of the harmonics of Si5351, it can use the 5th harmonic to measure up to 1.5GHz
- When fundamental wave is used, the output level of CH0 is increased to 0dBm, making reflection measurement more accurate
- Solved the abnormality of NanoVNA-H when operating at around 6MHz before
- Redesigned power management circuit reduces power noise, USB power interference, and charging current
- Improved PCB layout
- Reserved UART interface for DIY expansion
- Lightweight ABS shell keeps the device well protected

Test Short-wave Antenna:
- The yellow line pictured is the standing wave ratio.
- Note: As the SMA ports are made of cast copper, please not connect hard 50-7 / RG213 and other cables directly to the SMA ports through M-to-SMA connector to avoid damaging the SMA ports. You can use the included SMA cable to connect to the SMA port as shown in the picture below, and then use M to SMA connector.

PC Software:
Computer software supports control and real-time display. And it support for exporting Touchstone (snp) files for various radio design and simulation software.

As a measuring device, accuracy is of great importance. Simple calibration parts are included in the package. We have calibrated the product's dual ports before delivery. When your measurement conditions change (for example, switching from a narrower calibration bandwidth to a wider measurement bandwidth with an extension cable measurement), you need to re-calibrate. After calibration, it is saved as setting 0, which can be used directly at the next boot, or it can be saved to the other 4 saved items through recall when needed.
