Tektronix RSA5126B Spectrum Analyzer
Featured with 25, 40, 85, 125, or 165 MHz acquisition bandwidth, the Tektronix RSA5126B is a Real-Time Spectrum Analyzer designed to operate in a frequency domain from DC to 26.5 GHz. This model comes from the RSA5100B series and offers real-time signal processing with up to 3, 125, 000 spectrums per second. This speed enables the model to operate with 100% probability for 0.434 μs signals. The Tektronix RSA5126B comes with Advanced DPX technology and offers gap-free DPX spectrograms, DPX zero span, and swept DPX with real-time frequency, phase, or amplitude. While operating at 165 MHz bandwidth, this instrument can acquire more than 5 seconds.
The Tektronix RSA5126B has a definite advantage over convention instruments, since it offers a broad range of measurements, including but not limited to, CCDF, Spur Search, Channel Power, and ACLR. It can also display correlated, multiple domains. With the groundbreaking DPX® spectrum display, the user can see a live color view of signal transients as they change over time. The Tektronix RSA5126B offers some of the most potent and unique triggers like frequency, frequency mask, runt, and density triggers. These triggers have the potential to apply time qualification to the internal trigger sources, which provides the user with a chance to capture the "narrowest pulse" or the "longest pulse" in any pulse train.
At 2 GHz this model offers 20 dBm 3rd order intercept and –151 dBm/Hz displayed average noise level (DANL). The incorporated DPX display can represent transients with the least event duration of 3.7 μs. This model comes with a 10.4” touch-enabled screen, a simple yet effective control panel, USB ports, an Ethernet port, and GPIB interface.
