Built-in frequency reference using temperature compensated voltage-controlled crystal oscillator (&plusmn; 2.5 ppm VC-TCXO). <br />Dual IF design, IF and add / subtract mode can be individually preset. LCD0802 LCD screen display, up to 7 digits can be displayed, the frequency value is invalid zero automatic blanking. <br />Anti-power reverse design, low-power battery-powered programs. Double-button control, good man-machine interface. The settings are automatically saved, the next boot directly call. <br /> <br />Technical Parameters: <br />Gate time:0.64 sec <br />Measuring range: 1 MHz to 1.2 GHz <br />Measurement accuracy: &plusmn; 100Hz <br />Channel Sensitivity: (HM8134-2 data) <br />Test Frequency (MHz): 5 10 30 60 100 150 200 300 450 <br />Sensitivity (mV RMS): 35 20 10 3 3 4 8 15 12 <br />Test Frequency (MHz): 500 550 600 700 800 900 1000 1100 1200 <br />Sensitivity (mV RMS): 14 30 65 80 80 35 175 270 310 <br />Operating voltage:DC input: DC 9V ~ 12V (reverse polarity protection with power supply) <br />Operating current:Enable backlight: less than equal 55 mA <br />Display digits:The highest 8 digits are displayed <br />Physical dimensions:Length x width x height: 58mm x 32mm x 27mm <br />IF settings:IF adjustable minimum step of 100 Hz, the range of 0 to 999.9999 MHz, can be set to increase the IF or reduced IF mode. <br />Frequency reference:The 13000-MHz temperature-compensated voltage-controlled crystal oscillator (VC-TCXO) in a 5032 package has a frequency stability of &plusmn; 2.5 ppm. <br />Onboard interface: <br />RF INPUT (measurement signal input): XH2.54-2P square mouth socket <br />ICSP INPUT (MCU programming interface): XH2.54-6P pin <br />POWER INPUT (power connector): XH2.54-2P square port socket <br />size:58mmx32mmx27mm <br />Material:PCB+Plastic+Metal <br />colour:Green + Black <br /> <br />Package Contents: <br />1 x PLJ-0802-E frequency counter meter with cable <br /> <br />Only the above package content, other products are not included. <br />Note: Light shooting 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. </div></span> </div> </div> <div id="details"> <div class="ui-box-body"> <span style="font-size:18px;"> <table border="0" cellpadding="0" cellspacing="0" style="width: 100.0%;"> <tbody> <tr> <td style="margin: 0 auto; text-align: center;"><p></p><p></p><p></p><p></p><p></p></td> </tr> </tbody> </table> </span> <br /> <p> <br /> </p> <p> </p> </div> </div> </div></div></div>
