 Follow the below steps to configure the Multiplier block for an input signal of 4.75GHz (Tx signal of 19GHz): Follow the below steps to configure the Multiplier block for an input signal of 4.75GHz (Tx signal of 19GHz):
-  - Choose bias points from the dropdowns for the RF input buffer stages and click on the amplifier itself to enable the buffer. The buffer will change from grey to blue. +  - If the recommended bias conditions aren't sufficient, choose bias points from the dropdowns for the RF input buffer stages. Click on the amplifier itself to enable the buffer. The buffer will change from grey to blue. 
-  - Choose a bias point from the dropdown for the Mid-Band multiplier/amplifier and check the “Active” box next to the multiplier/amplifier. This will enable the circuit and change the input/output switches to the middle setting. The “Ready” checkbox should automatically be checked as well. The Mid-Band amplifier will change from grey to blue.+  - If the recommended bias condition isn't sufficient, choose a bias point from the dropdown for the Mid-Band multiplier/amplifier.

-  - Choose a bias point for the first active splitter and click on the splitter to enable it. The splitter will change from grey to blue. +  - If the recommended bias condition isn't sufficient, choose a bias point for the first active splitter. Click on the splitter to enable it. The splitter will change from grey to blue. 
-  - Choose a bias point for the second set of active splitters and click on the splitter leading to Channels 3 and 4 to enable it. The splitter will change from grey to blue.  +  - If the recommended bias condition isn't sufficient, choose a bias point for the second set of active splitters. Click on the splitter leading to Channels 3 and 4 to enable it. The splitter will change from grey to blue.

 To view the current Mode or State settings, first go to a sequencer programming tab at the top of the screen the two sub-blocks are labelled “Multiplier Block” and “Tx Block”. Choose a view type from the “Current View” box. The top checkbox will show the settings for the Modes. The middle checkbox will show the settings for the States. The bottom checkbox will show the settings from the current configuration. With the sequencer disabled, the “manual” settings will be shown. These are loaded from the SPI mode registers (0x45-0x48) With the sequencer enabled, the settings from the current index in the state machine will be shown. See “VIEW TYPE” in Figure 6 and Figure 8. To view the current Mode or State settings, first go to a sequencer programming tab at the top of the screen the two sub-blocks are labelled “Multiplier Block” and “Tx Block”.
