Discover

The DPX spectrum processing engine brings live analysis of transient events to spectrum analyzers. Performing more than 48,000 frequency transforms per second, transients as brief as 41 ìs are displayed in the frequency domain. This is orders of magnitude faster than conventional analysis techniques. Events are color-coded by rate of occurrence onto a bitmapped display, providing unparalleled insight into transient signal behavior.

Trigger

The Tektronix Frequency Mask Trigger (FMT, Opt. 02) makes it easy to trigger on signals in the frequency domain and capture transient signals in bandwidths up to 15 MHz. An FMT is simply configured to monitor all changes in frequency occupancy within the capture bandwidth. The Power Trigger, working in any capture bandwidth, fires at the instant in time when the RF input signal crosses a user-set power threshold. An external trigger is available for synchronization to test system events.

Capture

Unlike many SA/VSA combination instruments, the RSA3300Bs are fully preselected at all times for spurious and image rejection in any combination of capture bandwidth and frequency. Capture of small signals in the presence of large signals is enabled with 70 dB Spurious-Free Dynamic Range (SFDR) and class-leading image rejection in all capture bandwidths. Capture once – make multiple measurements without recapturing. Record lengths vary depending upon the selected capture bandwidth-up to 2.56 seconds at 15 MHz, 40.96 seconds at 1 MHz or 1.14 hours at 10 kHz bandwidth with FMT/Deep Memory Option 02.

Analyze

The RSA3300Bs offer analysis capabilities that advance productivity for engineers working on components or in RF system design, integration and performance verification, or operations engineers working in network or spectrum management.

• Spectrograms display both frequency and amplitude changes over time. Measurements are Time-correlated across the frequency, phase, amplitude and modulation domains.
• Analog modulation analysis and pulse analysis are standard.
• A wealth of modulation analysis supports are available, including the UMTS Family (3GPP HSUPA and HSDPA) and WiMax (Fixed and Mobile). General purpose modulation analysis includes support for M-QAMs, QPSKs and the latest RFID standards including ISO 18000-7 and 15963, plus signal source analysis including phase noise, jitter, and frequency-settling time. See specifications for details on measurement options.
