Scan exits to impedance mode showing the 2:1 bandwidth and the resonant point of the antenna CAN(up): increase frequency and used to cancel operation for CONFIG menu VAL(down): decrease frequency and used to validate operation for CONFIG menu
N1201SA Antenna Analyzer 137MHz to 2.7GHz
Description: N1201SA series is the handheld radio frequency vector impedance measurement analysis instrument, easy to use, simple operation. Built-in high capacity lithium ion battery for mobile and outdoor use. Shutdown automatically save settings parameter without human intervention, after starting up, interface settings completely the same as the power off before, use very worry. Can be used to test the antenna, the impedance of the radio frequency devices. For RF impedance measuring requires calibration, you need external calibration source. Specification: Working frequency: 140MHz~2700MHz Actual frequency : 137.5~2700MHz Stepped frequency: 1kHz Display: 2.4" TFT trdp Resolution ratio: 320 x 240(QVGA) Battery capacity: 2000mAH(7.4Wh) Power consumption: <1.5W Charge current: 400mA Charge port: USB Auto power off can be set 5-60minutes. Measured parameters: Resistence, Reactance, Standing wave, S11 Resolution ratio: 4 number Frequency accuracy: about 5ppm Connector: SMA-K Measurement range: Impedance: 0.1~1000 Standing wave: 1.000~65 S11(dB): 0dB~-60dB Working temperature: 0~40? Atmospheric pressure: 860hPa~1060hPa This instrument has four interfaces: single point measurement, scanning, system information, correction and calibration The default boot into single-point measurement interface. Note: For the convenience of the user, each time calibration correction options will automatically change to the user calibration. Meanwhile, in order to ensure the integrity of the calibration, the calibration process, the automatic shutdown function fails, the consistent boot. Startup and shutdown Hold down the CTRL key off press the power switch button. The boot state, long press (2S above) the switch button, after the release, the instrument will shut down. Recommended usage 1. In order to ensure the accuracy of measurement and calibration, preheat the instrument at least 15 minutes. 2. Try to use good quality RF cable and connectors. 3. Calibrated cable marked to the next may not need to calibrate and direct use. 4. Test cable process affect the measurement accuracy, it is recommended that, where possible, do not choose too long test cable. 5. Measurement and calibration before, make sure you are not in a strong wireless signal, so as to avoid interference caused by nearby RF sources. 6. If the impedance measurements are not as expected, you can refer to a vector network analyzer instructions and tutorials. This instrument is equivalent to a single-port vector network analysis. Package included: 1 x N1201SA ANT SWR Antenna Analyzer(English Version) 1 x Connecting Line
