请各位高手帮忙分析一下,我遇到一个奇怪的问题:射频项里的Carrier Frequency Drift测试无法测试通过,主芯片用的是CSR BC05-MM,附上的是完整的测试数据,还请高人能帮忙分析一下,先谢谢了!
【文件名】:09127@52RD_8.17 RF TEST.xls
【格 式】:xls

【目 录】:
_____________Carrier Frequency Drift (TRM/CA/09/C)
Initial conditions:
Test mode: transmitter test
Hopping: on
Packet type: longest supported
Payload: 1010 bit pattern
Number of packets: 10
Limits:
abs(f_drift_max) <= 40.0KHz, abs(drift_rate_max) <= 20.0KHz/50 us
Results (frequency drifts in KHz, drift rates in KHz/50us):
#ch f(MHz) f_drift_max drift_rate_max Verdict
0 2402 -19.1 29.9 FAILED
39 2441 -15.6 26.2 FAILED
78 2480 -7 -9 PASSED
Test time: 11 sec. |
