The -F V2 has been upgraded on the basis of -F to lastest Firmware 0.4.0, and the operation page is compatible with -F. It can measure S-parameter, voltage standing wave ratio SWR, phase map, group delay, chart, DELAY, , LINEAR and so on The -F V2 measurement range is 50KHz-3GHz, which is lager than the old version(previous is 10KHz-1.5GHz).The TX/RX can measure the complete S11 and S21 parameters,S21 dynamic ranges: 70dB (1.5GHz), 60dB (3GHz); S11 dynamic ranges: 50dB (1.5GHz), 40dB (3GHz) The Anterna analyzer uses all-aluminum alloy cases, which are sturdy and durable and can effectively shielded electtomagnetic interference to measurement accuracy. The radio frequency interface is SMA, which is convenient for connecting types of measurement Using PC software Saver, it can connect to the and extracts the data for display on a computer, and for saving to Touchstone files. Measurement frequency range:50KHz-3000MHz; RF output power:-9dbm (error within 1GHz: plus or minus 1db); Frequency accuracy:Less than 0.5ppm S21 dynamic range:70dB (1.5GHz), 60dB (3GHz) S11 dynamic range:50dB (1.5GHz), 40dB (3GHz) 2 Port return loss:20dB typ (1.5GHz), 13dB min (3GHz) 4.3-inch IPS LCD screen, IPS TFT (800x480) viewing angle close to 180, long-term use without hurting the eyes; Using a 5000mAh ultra capacity lithium battery, the battery life can reach 7 hours; Different batches may result in different product appearances, text, and colors, which do not affect usage Colour:Black Material:Metal Package Contents: 1 * Vector network analyzer(Kit) Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
