Error Add
Add errors to the data using the key and its menu of softkeys. There are three
modes of operation:
Single: Adds single errors on demand.
Fixed: Fixederrorratiosof1errorin10
n
bits, n = 3, 4, 5, 6, 7, 8, 9.
External: Injects a single error in the transmitted test pattern on each rising edge at
the ERROR INJECT INPUT port.
Clock and Clock (inverted) Outputs
The following clock output features can be set using the key and its menu
of softkeys.
• Clock high level adjust.
• Clock amplitude adjust.
• External termination voltage 0/−2V or ac coupled.
• External attenuator set 0 to 40 dB (0V termination only).
• Independent control of high level and amplitude for CLOCK and CLOCK.
