The default setup uses two ParBERT clock groups one to generate the MHL data signal and one to generate the MHL clock signal If you check the Same as Clock checkbox only one clock group is used for MHL data and MHL clock Note that applying intra pair skew to the MHL signals is only possible with this checkbox checked In addition to the ParBERT you have to connect the two Signal Generators These two instruments are used to generate the sinusoidal jitter and are connected by using VISA connection strings You find the right connection strings by using the Agilent Connection Expert that is part of the Agilent IO Libraries ParBERT Clock System Jitter Iniection Data System Jitter Iniection Sink Characteristics Signal Generator Signal Generator Termination Voltage TCPIPU 132 168 0 102 instO INS TF 192 168 0 103 inst INS TF 33V Setup Host Address 192 168 0 101 Clock System Gen DSRB Power Supply for Bias Tees Calibration Data Data System 1 Gen Power Supply Use Cal Data From Folder Same as Clock TCPIPO 192 168 0 104 gpib0 5 INS CAProgramData BitifEye WaliFrame Calibrations DSRA DUT Type Type FIGURE 3 CONNECTION DIALOG You can define a custom termination voltage This numeric value is used to calculate the actual voltage level applied to the generators If you have calibration data from the Agilent N5990A test automation you can use this calibration data in the MHL Fram
