Zigbee module performance test

ZigBee is a low-power LAN protocol based on the IEEE802.15.4 standard. According to international standards, ZigBee technology is a short-range, low-power wireless communication technology. This name (also known as the Zigbee Protocol) comes from the bee's splay, because bees rely on flying and "zig" to shake the wings of the "dance" to convey the position of the pollen with the companion. That is to say, the bees rely on such a way to form a communication network in the group. It is characterized by close proximity, low complexity, self-organization, low power consumption, and low data rate. It is mainly suitable for use in the fields of automatic control and remote control and can be embedded in various devices.

In short, ZigBee is a cheap, low-power, short-range wireless networking communication technology. ZigBee is a wireless network protocol for low-speed short-distance transmission. The ZigBee protocol is a physical layer (PHY), a media access control layer (MAC), a transport layer (TL), a network layer (NWK), an application layer (APL), and the like from bottom to top. The physical layer and the media access control layer follow the IEEE 802.15.4 standard.

First, the board will be tested for burning

1. Open the FlashGUI.exe software under the folder flashprogrammer. After the software is opened, the interface is as follows:

2. Click the Browse button on the FlashGUI.exe software interface to test the software.

slogan

2. Open the SecureCRT software - click

Button---Set as shown in the figure below, port number selection

Select the port number you see in the computer in the first step, then click OK.

Note: The checkmark of this option must be removed, or the serial port cannot be printed.

3. Click the connection button in the above figure, the serial port prints as shown below, and the board enters the test mode state.

Third, the current test

1. Deep sleep mode current test: Deep sleep mode : Expected value is 100nA

Remarks: Since there is no nA-class power meter, it is currently not tested. The current ST products generally can't do nA level, only UA can be used, and can be tested with a multimeter.

2. Sleep mode without memory retenTIon current test: Sleep mode without memory

retenTIon : Expected value is 600nA.

Remarks: Since there is no nA-class power meter, it is currently not tested. The current ST products generally cannot be nA level, only UA can be used, and can be tested with a multimeter. 3. After POR current: After POR: 4.5mA

Test method: to be determined

4. Radio Transmit Current: Radio transmit : 18.1 mA

Test method: to be determined

5. Radio receive current: Radio receive : 19.6mA

Test method: to be determined

Fourth, TX Frequency Accuracy test

1. Test the wiring diagram, open the SecureCRT software on your computer, and connect the computer and board with a USB cable.

2. In the serial port, set the board test mode as follows:

a) Standard Module---a) TX Power Test (CW)---- a) Output ConTInuous—Press +

Or - switch channels until channel18

3. Spectrum Analyzer Settings

Set analyzer to : Center frequency = 2.44 GHz , span = 2 MHz , Ref amp = 0 dBm 4. Test screenshot

6. Test result plan and expected value

Measured frequency : 2.440 GHz

Ppm value = (2440012 - 2440000) / 2.440 = 4.9 ppm "25ppm (AddiTIonal +/-15ppm allowance for temp. & ageing)

7. (test value - the center frequency of this channel) / the center frequency of this channel = a value, this value is required to be less than

25PPm meets the requirements

Five, TX Power test

1. Test the wiring diagram Figure 3. In the serial port, set the board test mode as follows:

a) Standard Module--- b) TX Power Test (Modulated)--- a) Output Continuous

2. Spectrum analyzer settings:

Start freq = 2.4 GHz , Stop freq = 2.5 GHz , Ref amp = 10 dBm , sweep time = 100 ms , RBW = 3 MHz

Click TRACE to enter, click Trace to set Max Hold mode

3. In the serial port, first switch the channel to 11, then press + to switch to channel26 and read the test result.

Click the MKR button, then click the MKR→ button, click the peak point and the next peak point to read the power.
