1.2.3.3.2 Macro Usage
Consider a use case where a tone at 2600 MHz with power of -4 dBFS needs to be transmitted out of
both 1TX and 2TX. It is assumed that the system is configured in the 1-kHz frequency resolution mode.
The TX Tone Generator Configuration Macro can used for this purpose as described in the sequence
below:
1. Save the TX12 Channel configuration and configure tone for 1TX. Note that configuration save
happens on entire TX side (that is TX12 or TX34), even if the tone is to be sent out of a single TX
Channel.
Table 1-53.
Operand Value Comments
1 0x00 Set TX Channel as 1TX
2 0x01 Save current 1TX and 2TX configuration and apply new
configuration for 1TX. Note that configuration save always happens
on a pair of TX Channels (that is TX12 or TX34).
3 0x00 RESERVED
3 0x04 Tone power = -4 dBFS.
4 0x0027AC40 Tone Frequency in kHz.
5 0x00 RESERVED
6 0x00000000 RESERVED
2. Configure tone for 2TX.
Table 1-54.
Operand Value Comments
1 0x01 Set TX Channel as 2TX.
2 0x02 Apply new configuration for 2TX. Note that we should NOT call save-
configuration command here as the save has already happened in Step 1.
3 0x00 RESERVED
3 0x04 Tone power = -4 dBFS.
4 0x0027AC40 Tone Frequency in kHz.
5 0x00 RESERVED
6 0x00000000 RESERVED
3. Once the desired operations with the tone signals are done, the TX channel settings can be restored.
Table 1-55.
Operand Value Comments
1 0x00 Set TX Channel as 1TX
2 0x04 Restore TX channel 1 and 2 configuration.
