EV9902A Datasheet, PDF (15/23 Pages) CML Microcircuits – Measures Bit Error Rate

Interface Kit for EV9900A
EV9902
• the Main and Aux PLL divider registers
• the Analogue Setup registers
• the Control register
• the ‘INV’ and ‘Scram En.’ bits of the Mode register.
• the Clock Control register
The value of all the other CMX990 registers will be set to the default regardless of the selected
option. Each time a frame transfer is performed the ES9902 application will update the displayed
register values to reflect those written to the CMX990.
NOTE: If the default reference clock is not to be used for the modem transfers, it is
important to set the ‘Reference Clock (MHz)’ value, shown in the ‘PLL Regs’ tab, to that of
the reference clock to be used.
6.1.6. The Script Handler Tab
The Script Handler tab allows the execution of script files consisting of register write and read,
delay and wait on IRQ commands, see Figure 8.
