TEGA UHF Characterization

Reconciled with block: tega_uhf_char_r4

Objectives:

Power on and perform a ramp during a UHF pass.

Configuration:

Inputs:

Filament = 1

Multiplier Voltage: = 3300

Pre-heat duration: minimum 30 seconds

Select TA #: oven_ID = ____

Ramp_time = 3003

Pass_duration = 900

Constraints: Start 15 minutes before the start of the pass

Gases Used: None

Filaments Used: 1

LOW Emission

SW Version (386) V513 SW Version (EGA): V321

Sweep and hop mode version(s): MODE TABLE V123

Super modes and Sweep modes used: Supermodes 1, 14

Supermodes running in ramp: 14

Note: TEGA is checked to see if TEGA is safed. If so, abort self to end activity
