Figure 77. Timing Parameters Configuration in TES
As shown in Figure 77, only relevant channels are enabled for timing parameters configuration. User should enter all the values in ns. The
propagation delay is a helper parameter, which is not needed by ADRV9001. It helps to set other timing parameters ADRV9001 requires.
As aforementioned, API Command adi_adrv9001_Radio_ChannelEnablementDelays_Configure( ) can also be used to set the timing
parameters. As a summary, all the APIs provided for timing parameters are listed in Table 29. Refer to the API doxygen document for
more details.

API Function Name
Description
adi_adrv9001_arm_ChannelPowerSaving_Configure
Configures the channel power saving settings for the specified channel.
adi_adrv9001_arm_ChannelPowerSaving_Inspect
Inspects the channel power saving settings for the specified channel.
adi_adrv9001_Radio_ChannelEnablementDelays_Configure Configures channel enable delays for the specified channel.
adi_adrv9001_Radio_ChannelEnablementDelays_Inspect
Inspects channel enable delays for the specified channel.
Pin control mode timing measurement
ADRV9001 receives Tx/Rx Enable control signals and the related user’s timing parameters to perform the Tx/Rx RF On/Off operation in
pin control mode. As previously mentioned the enableSetupDelay (EnaSetup) is the time taken for ADRV9001 to power up its analog
front end, and ADRV9001 will also take small time to finish the operations to power down its analog front end at the falling edge of the
Tx/Rx Enable signals, users should be advised the programable “EnaRise2AnaOn” and “EnaFall2Off” will delay the Adrv9001 analog
components power on and off respectively. The enableSetupDelay varies with different ADRV9001 internal processor clock rate. Users
can enable the ADRV9001 internal stream status to GPIO debug function to accurately measure the Tx/Rx enable control signal and
when they are actually taken effective by ADRV9001 internal stream processor.
