CC8531: Not able to output RF CW signal constantly

Dear TI wireless experts:

We just finished a product prototype using CC8531 + CC2592 to achieve wireless audio bi-directional transporting.

All functions of the chipset looks good, link distance is acceptable (>10m under crowded Wifi inteference).

For further RF testing, we need to let CC8531 output continuous CW RF signal so the RF power spectrum can be measured and analyzed.

We have tried PPW Commander as per TI website and support forum recommened, but failed due to some problems:

1, We've tried Production Test in PPWC, a simple xml is created to call function simpleRfTest() to generate CW output in certain frequency, but the maximum length is 1000 samples only, so the RF signal generated and dissapeared very quickly, our spectrum analyzer is difficult to capture a stable measurement.

2, We've tried RX/TX test in PPWC, basically same problem as above, after configured CC8531 to TX and click the "Start", the available duration of RF signal is very short, cannot be captured and measured. BTW, another probable SW bug is observed: When CC8531 is configured as RX, and click "Start", after a few seconds, the RX ISSI curve may become weird and an error reported, then RX test aborts.

3, We've tried using script in PPWC. A simple script is created as below, but always PPWC reports error "Script execution failed ..." when executing rft_txtst_cw(0, enable, 122, 0).

set_timeout(1000000);
id("master");
sys_reset();
wait(10);
rft_txtst_cw(0, enable, 122, 0);

Is there any idea to set CC8531 in stable and constantly CW output mode? Otherwise RF performance evaluation is not possible.

Thanks in advance.
