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 AnalyzerMaterial: ABSRated Frequency: 10k to 1.5ghzScan Points: Up to Three Hundred and One PointsBattery Capacity: 5000mah 3.7v 6060100 Lithium Battery x 1 (Shipped with Built in Battery)Memory Size: 16mbUp to About 1000 Sets of Snp File Data can be Saved.Package List:1 x Analyzer1 x Screen Protector2 x Screen Cleaner1 x USB A to USB Type C cable2 x 20CM SMA Male to Male RG316 RF Cables1 x SMA Male Alignment Sheet OPEN1 x SMA Male Alignment Sheet SHORT1 x SMA Male Alignment Sheet LOAD1 x SMA JJ Male to Male Connector1 x SMA KK Female to Female Connector1 x SMA JKW Male to Female Right Angle Connector1 x Foldable Stand1 x Resistive Screen Stylus1 x Manual1 x Storage BagNote:1. 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.
