RADIASUN Devliver Reliability and Trust AV4022 Handheld Spectrum Analyzer Key Features AV4022 is a high performance portable spectrum analyzer. It has adopted a lot of advanced technologies in the industry, for example the all locked—phase local and the all—digitized medium frequency processing technologies. All RBW/VBW filters and medium frequency/video detectors are employing digital methods to reach a higher technical level. While boasting the performance of a table analyzer, AV4022 excels in its small size, lightweight and good mobility. With large capacity rechargeable lithium battery inside, it is a good choice for premises where no external power supplies are available. The internal non—volatile memory can store 200 measurement data, which can be downloaded to a PC through RS232 for future management, saving and printing. The 6—inch VGA TFT color LCD is convenient for observation of signal details. 1. Frequency Range: 9kHz ～ 3GHz 2.

Dimensions circa: 175×280×80mm 23. Environment Adaptation conforms to thir-level equipment standard in GJB39472000 2 The AV4022 Portable Spectrum Analyzer is easy to be operated. It can either be laid flat or be stood up using the foldout support at the back. It can be laid flat for operation from above. Because the grip is slightly raised at the back, the AV4022 is tilted forward to give the optimum-viewing angle for the display. Front Panel Details 1). Softkeys Each key is relative to some softkey on the display. 2). Function keypad Including set and measure areas. The before has Freq, Span and Ampl, which are the basic parameters. The later has Frequency marker, Peak, Limit and Ampl. Marker can read frequency and amplitude of the line and mark the maximum values and auto-track the signal. 3). Cursor keys “?” and “?” control step or UP/ DOW N choice; “?” is back key and deletes a number or character. 4).Numeric keyboard Through this keyboard to input a number or change one to another number. 5).On/off button. 6). Run/stop key: Sweep mode is single, to press it for one sweep. 7). Preset key: Return the default state. 8). DC Jack: DC power supply input jack,connect to AC supply through an adapter. 9). Rotary knob: Change reference parameter and modulate them. 10).Enter key. 11).RS232 serial interface. Connect with communication cable to download measure data to your computer and upload antenna factors. 12). Cancel key 13). Connector for headphone. The diameter is 3.5mm 14). Menu: Return to the default menu. 15). LCD. 16).RF input N connector. Through the cable, Input RF signal to RF Input port, which allows the maximum power 27dBm (500mW ). Within 3 seconds, power can reach to 30dBm (1W ) and lead to overload; if it lasts long time the spectrum analyzer will be damaged.

After setting step frequency, if you want to change other frequency parameters, you can modulate rotary knob and the cursor to the frequency you expected. Span The span menu is used to set the frequency range over which the instrument will sweep, the span can be set from 10 kHz to 3GHz. Press [zero span] softkey to set the span to 0Hz. Amplitude Parameters Press Ampt to set reference level, whichis the top graticule line on the display,and canbe set from +20dBm to -50dBm. The default unit is dBm and dBV, dBmV, dBuV are optional units. You can point the default unit by softkey [amplitude unit]. Scale decides resolution of Y-axis. The unit of Sacle is dB. Default scale value is 10dB, also can be set to 5dB,2dB,1dB,0.5dB,0.2dB and 0.1dB. Bandwidth RBW(resolution bandwidth) RBW decides the minimum frequency interval between two equip-amplitude signals. Resolution bandwidth of the AV4022 spectrum analyzer steps from 100Hz to 1MHz with step 1, 3 and 10. The default RBW is automatically adjusted and relative to span. RBW automatically reduces when span get small. Video bandwidth Video bandwidth can decrease noise floor and smooth trace, IF signal after filtering and envelope demodulation becomes video signal and envelope signal Video bandwidth of the AV4022 spectrum analyzer steps from 10Hz to 3MHz with 1, 3 and 10 step. The default video bandwidth is automatical relative to resolution bandwidth. 4 Marker Press Marker key to open the Marker menu.The AV4022 spectrum analyzer is equipped with five markers. Basic Mark set Mark 1 owns the functions of Max, Min and Mark To Center. Delta marker set Input frequency difference value on numerical area and press GHz, MHz, kHz or Hz. It displays frequency difference between Mark 2 and Mark 1 on the right of the grid window. Amplitude unit is the same with reference level. Marker auto-locating function Mark 1 has auto-locating function for easy operation, including peak value, sub-peak value, and left neighbor and right neighbor peak value. Harmonic Measurement Since a spectrum analyzer can measure many different signals in frequency domain,it is ideal for measuring harmonic level and harmonic rate. A signal generator with 100MHz output frequency and 0 dBm output level is used in the following measurement example. Save measure data The AV4022 spectrum analyzer can save the measure marker and measure state, and it is connected to PC with a series communication cable for downloading. The instrument can save up to 100 traces and 10 instrument states that are available for any load. Download measure data You can connect one port of a series communication cable to the serial port of the spectrum analyzer and the other port of the cable to PC. Then the stored tracescan be downloaded to your computer by the specific software provided with the instrument. Upgrade via PC. The firm ware of AV4022 can be upgraded via PC when the meter is linked by communication cable. You can get the upgrading software from service center of download it from the Internet.
