TYPE-C RF Power Meter (RF-Power-Meter-V7.0)

1. Product Overview

Advantages of RF-Power-Meter-V7.0 RF Power Meter

1. Supports multiple high-speed dynamic acquisitions, with a maximum of 500kbps (2μS) for host computer acquisition.
2. Supports RF signal acquisition up to 10GHz.
3. Has a built-in digital programmable attenuator (0 - 31.75DB). When used with the digital control attenuator, the maximum measured input power is 30dBm (1W), and the dynamic range is from +30dBm to -60dBm.
4. The V7.0 power meter comes with a 1.3-inch TFT LCD and a built-in Li battery, enabling offline operation.
5. Uses a 4-pin aviation plug to provide TTL serial port read and write functions, and offers single-shot and continuous data reading modes.
6. The host computer has 2 MARK cursor functions, facilitating the measurement of modulation pulse width; it can automatically calculate the maximum and minimum values, with a maximum storage depth of 500 points; it also supports pause, data saving, and export functions.
7. The RF input interface is an N-type male connector.
8. Booting process: Check if the battery switch is in the ON position, then press the middle button on the panel, and finally, long-press and slide the right arrow key.
9. Shutdown process: Long-press the middle button to turn off the device.

3. Product Technical Specifications

1. Measurement power range: -60 to +30dBm (excellent linearity from 0 to -40dBm. When the input signal is greater than 0 to +30dBm, the internal digital control attenuator can be set as ATT = 30DB and OFFSET = +30DB, and the measured power value will be displayed after actual measurement).
2. Measurement power resolution: ±0.1dBm.
3. Measurement frequency range: 100K - 10GHz (the frequency range varies for different models).
4. Input impedance: 50Ω.
5. Dynamic range: 90dB.
6. Operating voltage: 5VDC (powered by a TYPE-C cable).
7. Charging current: 300mA.
8. Dimensions: 66*36*24mm (excluding the protruding N-type connector; refer to the provided mechanical drawing for details). The body is made of a fully numerically controlled aluminum alloy shell, and the weight is less than 100g.
9. Shipping list: 1 host with an aluminum alloy shell + 1 TYPE-C cable.
10. TFT display information instructions:
    • Freq: Frequency setting. This data is input via buttons and is used to calibrate the detection error at different frequencies, not the value measured by the power meter.
    • Power: Measured power value in units of W.
    • dBm is defined as miliwatt. 0dBm = 1mw.
    • dBW is defined as watt. 0dBW = 10lg1W = 10lg1000mw = 30dBm.
    • ATT: Value of the internal digital control attenuator of the power meter. The attenuation range is 0 to 31.75DB. This value needs to be set when measuring signals greater than 0dBm to improve measurement accuracy.
    • Offset: Linear offset setting value.
      • First function: When ATT is set, the offset needs to be set through offset.
      • Second function: Calibrate the interface error.
      • Third function: If an external amplifier or a standard signal source is added, the relative error can be set using this value.
    • 95% internal lithium battery power reminder, IC000 machine internal address.

4. Host Computer Communication Mode (In the high-speed mode of the host computer, the TFT LCD and TTL serial port communication are unavailable)

5. Offline Mode (When not using the high-speed mode of the host computer, the TFT LCD and TTL serial port communication are used for data display and transmission)

• Example: IC001+S: Send data every 10ms.
  6.3. IC+SAVE+001+002: Change the IC address, with the old address first and the new address second.
  6.4. IC001+W±02.2+01.25+1000: Data modification, which are (you can choose the plus or minus sign) OFFSET value + ATT value + FREQ value respectively.
• If the ATT value does not follow a 0.25-step entry, the lower computer only takes the value before the decimal point. For example, if 03.89 is input, the lower computer will only store the ATT value as 03.00.

• IC000+R
  • Note: The default IC address of the machine is 000, and the end symbol is "carriage return". To read the power value, the returned data is:
  • Level: 60.8 dBm
  • Power: 000.00 uW
• IC000+X
  • ATT (fixed attenuator value): 00.00 dB
  • FREQ (frequency value): 800 MHz
  • OFFSET (offset): -00.0
• IC000+L, IC000+S, IC000+T
  • IC000+L: Upload low-speed data directly (upload one data every 0.5S).
  • IC000+S: Upload high-speed data directly (upload one data every 1mS).
  • IC000+T: This command is required to stop the upload of low-speed or high-speed data, and the return is USART_Stop:0.
• IC000+W-10.0+20.25+0800
  • Write the OFFSET value, ATT value, and FREQ value for IC000. The OFFSET offset value is -10.0DB, the internal digital control attenuator ATT attenuation value is 20.25, and the frequency is 800MHz.
