One unique service Teledyne RF & Microwave offers is the ability to individually match a gain characteristic to a given tube's performance. This is done using Automatic Test Equipment (ATE) to calculate the gain needed at any particular frequency in order to maintain an overall flatness across the whole operating band. This is done without the need for the tube to be provided to Teledyne; all we need is the gain characteristics of the individual tube.
Many gain shapes are available to compensate for many different interactions with gain.
