Holzworth Phase Noise Measurement Analyzers
Holzworth Instrumentation was founded as a phase noise measurement company. Along the path to phase noise analysis solutions, our high performance building blocks were developed and sold in the form of RF Synthesizers, Phase Detectors, etc. The HA7401A is a Fixed Frequency Phase Noise Analyzer, and the HA7402A is a Phase Noise Measurement Engine.
The HA7401A Fixed Frequency Phase Noise Analyzer measures the phase noise of single-frequency signal sources at 10MHz, 80MHz or 100MHz. Rugged enough for portable, on site testing of distributed references, yet stable enough for advanced R&D testing. Targeted for high speed throughput of extremely low noise oscillators, synthesizers and calibrated references. The HA7401A is ideal for OCXO and TCXO design and manufacturing test.
The HA7402A Phase Noise Measurement Engine is Holzworth’s two-channel, cross correlation core with the addition of fully programmable PLL's and three frequency counters. It tunes to the DUT, based on the non-coherent LO inputs (LO1 & LO2). The HA7402A is the first in a series of phase noise engines, allowing for DUT testing from 10MHz to 1.2GHz.
The core engine combines the performance of the HA7401A with the LO frequency as provided by the customer. Ideal for OCXO/TCXO manufacturing and R&D testing where high levels of throughput are required. The engine offers pure measurement performance and speed with the flexibility customer set test frequencies. Auto-Selectable PLL's coupled with software defined, auto-detect/auto-lock of the LO signals and DUT; simplifies the test solution in comparison to any other phase noise measurement test set.
