IntroductionSeveral industry and standards bodies have defined specifications for 100 Gb/s highspeed electrical interface using PAM4 coding. As an example, an implementationagreement (IA) developed by the Optical Internetworking Forum – Common ElectricalInterface (OIF-CEI) defines 112 Gb/s operation in OIF-CEI 112G using 53/56 PAM4signalling (CEI-112G-VSR/MR/LR).The Keysight N109212CA OIF-CEI-112G software is a measurement application forthe DCA-X equivalent-time sampling oscilloscopes designed to save time and moneyby automating the task of performing PAM4 transmitter (TX) test measurements.Find us at www.keysight.comKeysightN109212CA OIFCEI-112G softwareThe KeysightN109212CA OIF-CEI112G software is ameasurementapplication for theDCA-X equivalent-timesampling oscilloscopesdesigned to save youtime and money byautomating the task ofperforming Pam4transmitter (TX) testmeasurementsPage 3

Configure Your Solution in Three WaysThe hardware and software architecture provides wide flexibility. The N109212CA TX test applicationmay be run as follows:1. N1000A DCA-X runs the N109212CA application locally and controls remote PNA via LAN2. PC runs the N109212CA application and controls remote N1000A DCA-X, PNA via LAN3. PC runs both N109212CA and N1010A FlexDCA software applications and controls remoteN1000A DCA-X and PNA via LANThis lets you use your PC for additional processing power and other applications, or you can have all the measurement capabilityconsolidated into a compact solution. For return loss measurements, the N109212CA application can control an N1055A TDR orPNA vector network analyzer to perform measurements automatically.Figure 13.
