Feature: 1. Scope of Application: This vector network analyzer can measure circuit s parameters, transmission tests, reflection tests, insertion loss, return loss, fault location (tdr function), antenna standing waves, impedance, filter response, and more. 2. ABS Shell: Made of ABS shell, our analyzer possesses strong anti interference ability, wear resistance, impact resistance, comes with a long life span. 3. 4.3in Screen: Equipped with a 4.3in screen and touch screen pen, this analyzer is more accurate and easier to operate. 4. Powerful Endurance: This vector network analyzer is battery powered or USB powered. A built in 5000mah battery can provide longer battery life, and the analyzer can be connected to a power bank or power supply if you need extra working time. 5. Better Performance: The user key of the analyzer is changed to a rotate encoder, the control is more convenient and smoothly, the s21 insertion loss is optimized, the filter measurement performance, and the dynamic range is larger. 6. Additional Information: Increase RTC real time clock, perpetual calendar function. The measurement data file name format is yymmdd_hhmmss. Frequency adjustment can choose start stop or center extension. Boot sound can be turned on or off. Specification: Item Type: Vector Network Analyzer Material: ABS Rated Frequency: 10k to 1.5ghz Scan Points: Up to Three Hundred and One Points Battery Capacity: 5000mah 3.7v 6060100 Lithium Battery x 1 (Shipped with Built in Battery) Memory Size: 16mb Up to About 1000 Sets of Snp File Data can be Saved.

The working principle of the resistive touch screen is mainly to realize the operation and control of the screen content through the principle of pressure sensing.2. Installing a screen protector will have a certain impact on the operation of the touch screen, unless it is necessary, we recommend that you do not install a screen protector.
