Question about VGA parameter in Transceiver Toolkit (Quartus Std 23.1)

Hello,

I am using Transceiver Toolkit in Quartus Prime Standard 23.1 (Build 993). I can get and configure the Variable Gain Amplifier (VGA) parameter in the GUI, but I cannot find any corresponding command in the documented Transceiver Toolkit scripting API.

From the documentation (683552 - 2018.09.24), I can use the following commands (get & set):

transceiver_channel_rx_get_dcgain
transceiver_channel_rx_get_eqctrl
transceiver_channel_rx_get_dfe_tap_value

However, there is no mention of VGA.

Could you please clarify whether VGA is mapped to another parameter, or if it is not accessible via scripting?

Thank you for your support.

Best regards,
Huy HO.
