LMX9838DONGLE: Test modes

Part Number: LMX9838DONGLE

Hello,

I am in progress of testing/validating the old lmx9838 chip.

Our test house wants to test a center frequency of a BT channel on the module.

I think we have tested most of the configuration options of the RF_TEST_MODE command ( table 274 in section 7.2.19.2 Initiate RF Test Mode of the AN-1699 LMX9838 Software User's Guide) in order to get the chip to send out the center frequency of a BT channel.

The best approximation I could get was to use test mode 0x3 with fixed 0 and 1 modulation and calculate the average frequency to estimate the center frequency.

The test house insists on having direct measurement on the center frequency.

Are there any configuration options that allow the lmx9838 to continuously send the center frequency of a BT channel.
