NanoVNA-H4 50KHz~15GHz VNA HF VHF UHF UV 4-inch LCD Vector Network Analyzer
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 Computer software supports control and real time display And it support for exporting 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 Parameters 1 ABS Shell 75mm x 133mm x 18mm excluding protrusions 2 Measurement Frequency 50KHz 1 5GHz3 RF Output 0dbm
