Description
Applications:
● Calibration of RF instrumentation equipment;
● detection and maintenance of RF equipment;
Measurement of standing wave ratio of RF circuit (adding feedback bridge);
● Measurement of return loss of RF circuit;
● interference detection between wireless communication devices;
● RSSI (received signal strength indication) and transmit power level detection;
• Performance evaluation of step attenuators;
● Amplifier gain and network attenuation measurement;
• Measurement of forward power and reflected power in the directional coupler;
● GMSK modulation of the GSM signal power measurement *;
The product technical indicators:
1, measuring power range -60 ~ +0 dBm
2, measuring power resolution : < ±1dBm
3, measuring frequency range 100K ~ 3000 MHz
4, the input impedance of 50Ω
5, the dynamic range> 60dB
6, the working voltage 5VDC (through micro-USB power supply)
7, operating current <50 mA
8, size 68 * 48 * 18 mm (length X width x height)
How to use:
1. Power supply: Connect the power supply (signal source, computer, charging treasure, etc.) via micro-USB.
2, the power switch: next to the USB, the switch to the left to turn on the power, turn to the right to shut down.
3. Input: Connect RF signal through SMA1 interface, SMA2 is the detection voltage output for secondary development.
4. After powering on, press the “OK S3” button to initialize the power meter.
5. Press the button S1 to change the position of the cursor (shift left)
Press button S5 to change the position of the cursor (shift right)
Press S2 to change the data of the cursor position plus
Press button S4 to change the data of the cursor position minus
After entering the system, the cursor indicates the selected digit. At this time, the up and down buttons can modify the value of the selected digit. When the cursor is at the last digit (or first digit) of the selected item, press the right button (or left button) to toggle the selected item. When the parameters are set, press the middle OK button to make the settings take effect.
Note: For details on how to use the power meter to connect the computer to the host computer software, see “How to use the host computer”.
Offset: Provides the offset selection for both "positive" and "negative" symbols.
Here are three common scenarios where preset offsets are required:
1 signal is too large, add attenuator between the signal source and the power meter, the offset is set to the attenuation of the attenuator, the symbol is "positive" 2 signal is too small, add amplifier between the signal source and the power meter, partial The setting is set to the gain of the amplifier. The symbol “negative” 3 signal has loss (attenuation) between the signal source and the power meter, and the offset is set to the attenuation of the signal, and the sign is “positive”.
