Automation Xpress Interface (AXI) (Option 48)
For use with Giga-tronics Automation Xpress software. The AXI
provides Xpress 2.5 ms CW Frequency/Power switching, faster data
exchange and functional downloads/executions, and a stable API
programming interface for the ATE programming environment.

5 Time for frequency to settle within 50 kHz of final value after a frequency switch.
6
∆ F0 = | (Fstop x Nstop) – (Fstart x Nstart) | - See Frequency Bands Table for N values.
7 Time for amplitude to settle within 0.1 dB of final value after an amplitude switch.
8 Delay is specified from edge of trigger pulse.
9 Modulation peaks must be less than maximum available power.
10 Levels noted can be offset using step attenuator (option 26).
