The Keysight E4438C is an ESG vector signal generator that provides both analog and vector signal generation capabilities up to 6 GHz. It supports Dual ARB waveform playback and is compatible with Keysight Signal Studio software for creating, downloading, and playing back complex modulated waveforms for wireless communications testing.
The E4438C features a Dual ARB (arbitrary waveform generator) mode that allows users to select, play, and evaluate complex modulated waveforms. Waveforms can be stored in both volatile waveform memory (WFM1) and non-volatile waveform memory (NVWFM) for permanent retention across power cycles.
Yes, the E4438C ESG is fully compatible with Keysight Signal Studio software. Users can connect via LAN to configure, generate, and download waveform files directly to the instrument. The E4438C also supports waveform licensing with 5-pack or 50-pack waveform license slots for permanently locking waveforms to the instrument.
Waveforms can be loaded onto the E4438C via a live LAN connection using Signal Studio software, which allows direct download to the instrument. Users configure waveform parameters in Signal Studio, then click Generate and Download to transfer the waveform file into the instrument's volatile memory for immediate playback.
The E4438C supports 5-pack or 50-pack waveform licensing, allowing users to permanently lock Signal Studio waveforms to individual license slots. Each slot provides a 48-hour trial period for waveform evaluation before locking. Once locked, the waveform is permanently licensed to the instrument.
To evaluate a waveform, press Mode, then Dual ARB, then Select Waveform and choose your waveform file. Set the ARB to On, configure the desired carrier frequency and amplitude, then turn RF On to output the signal. Each waveform slot provides 48 hours of trial time for evaluation before requiring a permanent license lock.
The E4438C is a vector signal generator, meaning it can generate both CW (continuous wave) signals and complex digitally modulated waveforms using its built-in Dual ARB. This makes it suitable for testing wireless communications receivers, simulating various modulation formats, and evaluating RF device performance up to 6 GHz.
The E4438C uses two levels of waveform storage: volatile waveform memory (WFM1) for temporary waveform playback and non-volatile waveform memory (NVWFM) for permanent storage. Before licensing a waveform to a slot, it must first be saved to NVWFM using the Store Segment to NVWFM function under the Dual ARB menu.
