Fixture requirements:
1. Smart Carrier (RIK0014A or B).
2. Press in connector strips ( 16 pin ) installed at desired module locations ( M1 - M8 ).
3. Bench Top DC Voltage Requirements: +5V / -5V / +3.3V ( 3.3V only required if running LNA)
Coding Requirements:
Fixture Carrier Position# | Switch Code Prefix |
M1 | S1 |
M2 | S2 |
M3 | S3 |
M4 | S4 |
M5 | S5 |
M6 | S6 |
M7 | S7 |
M8 | S8 |
RF Attenuator Control Programming:
1. When writing to a Smart Carrier Cbit the format is of S#XXXX
S = S, # = Module number being written to, X = 1, X, or 0.
0 = closed (0V) and 1 = open (3.8V)
Bit position = S# DS1 DS2 DS3 DS4
