Selecting Option 502 for the E4438C ESG vector signal generator provides a 250 kHz to 2 GHz frequency range. Five frequency range options are available to choose from, extending from 1 GHz up to 6 GHz maximum carrier frequency. This provides ample resolution to configure the ESG to meet your specific test requirements.
The 250 kHz to 2 GHz frequency range, combined with the advanced internal baseband generator, provides an economical alternative to configure the ESG as a high-performance arbitrary waveform generator and real-time I/Q symbol builder. This enables the creation of benchmark test signals at baseband and RF frequencies up to 2 GHz.
When combined with the N5102A Baseband Studio digital signal interface module, mixed-signal testing with digital and analog baseband, digital and analog IF, and RF test stimuli are all easily realized. More information
Option 502 is recommended for test cases that require baseband and RF test signals at or below 2 GHz carrier frequency. Common uses include test stimulus generation for various components used in wireless communications systems transceivers, such as ASICs, DSPs, ADCs, DACs, up/down converters, filters and power amplifiers. In addition, the 2 GHz frequency range enables the generation of receiver test signals at low- and mid-band cellular frequencies, including W-CDMA, cdma2000, and GSM.
