SV4401A VNA 50KHz-4.4GHz Vector Network Analyzer 100dB Dynamic 7inch Touch Lcd Firmware upgrade Product Performance: 1. Measuring frequency range: 50KHz-4400MHz; 2. RF output power: -12dbm to -42dbm adjustable (step 1db) (error in the full frequency band: plus or minus 1db); 3. Frequency accuracy: ± 1ppm 140MHz 4.S21 Dynamic Range: 90dB (below 2GHz), 75dB (4.4GHz) (turn on 25x averaging and 100Hz IF), if you turn on the IF 100Hz and 25x averaging, you can achieve 100db dynamics below 1.3GHz. 5.S11 dynamic range: better than 50db 6.2 Port Return Loss: 30dB typ (1.5GHz), 20dB min (4.4GHz) 7.USB Interface: USB Type-C Communication Mode: CDC (Serial) 8. Number of calibration points: 101-1001 points 9. Number of scanning points: 101 points-1001 points 10.Display trace: 7 traces 11. Mark: 8 mark points (mark mark bar can be moved anywhere on the screen) 12.Setting save: 12 (shortcut menu) (save the next time you turn on the use can be directly called, without the need to calibrate from the new, the next time you turn on the power to automatically call the last time before the power off of the saved parameters, and increase the automatic storage of the starting and stopping frequency of the function, convenient for the next time to call) Built-in file saving, in principle, you can save unlimited number of storage units, according to the capacity of the TF card. 13. Scanning speed: about 400 points/second 14. Can measure S-parameters, voltage VSWR SWR Smith's circle diagram Phase diagram, group time delay, TDR function ......; 15. The use of 7-inch high-brightness IPS capacitive touch screen, IPS TFT (1024x600) viewing angle close to 180 °, long-time use does not hurt the eyes; (outdoor can see the curve, at present, such hand-held vector network in the screen brightness of a higher one) 16. The use of metal chassis, effective shielding of electromagnetic interference, making the S21 in the 2GHz is better than 100dB of dynamic range 17. Compact design, body size 195mm * 150mm * 35mm, compact and portable; Packaging size: 300 * 200 * 90mm 18. RF interface for L16-F (N female), easy to connect all kinds of measured parts; 19.

Support screen shot, support screenshot uploading to computer. Can test ①VSWR and impedance of antenna; ②Insertion loss, isolation, standing wave of filter; ③ The attenuation, shortening factor , phase of the cable; ④Amplification of antenna amplifier; ⑤ Cable length Frequency meter function; Group delay function is powerful; The key is that you can also debug the uv-band frequency duplexer Firmware upgrade method Connect the computer with a data cable, press and hold Ctrl and then turn on the computer, click Udisk of Vector Network Analyzer, you will see a u-disk on the computer, copy the upgrade file to that u-disk, overwrite the original file, turn off the computer, press and hold Ctrl and turn on the computer, a dialog box will pop up, click Upgrade to upgrade, wait for the completion of the shutdown and then turn on the computer again. Special Note: If you meet the u-disk does not show up after connecting to computer, please fully charge it first before connecting to computer to enter the u-disk mode. Because once connected to the computer will be charging, some usb with load capacity is not good will cause the computer to exit the usb mode caused by connection failure.
