Modulation Distortion Up To 13.5 GHz
S930701B
S930701B enables fast and accurate active-device modulation distortion characterization under modulated stimulus condition up to 13.5 GHz. The wide dynamic range and vector error correction of the PNA-X result in an extremely low residual EVM of the test setup, so you can get a complete picture of your device’s performance without test system interference. S930701B can measure EVM, NPR, ACPR, and can decompose nonlinear signals and linear signals with the spectral correlation between input and output spectrum without doing demodulation. Integration with the PNA-X SCCM provides quick modulation distortion measurements while making other VNA measurements.

ACCUplace Dot Distortion Target
AP-DD Series
All machine vision lenses will show some type of distortion. Minimizing or correcting that distortion is crucial in most applications. The ACCUplace Dot Distortion target is designed to detect the presence of both barrel/pincushion distortion as well as alignment distortion that causes the keystone effect. The precise amount of distortion is determined from an array of precisely placed dots in a regular array. The results can be used to correct for any distortion that occurs within the optical system. The AP-DD is offered on three standard substrates; Chrome on Glass (CG) Opal (OP) and Photo Paper (RM).

1 GHz, 1 MΩ, 0.9 pF Active Probe
ZS1000
Engineers must commonly probe high frequency signals with high signal fidelity. Typical passive probes with high input R and C provide good response at lower frequencies, but inappropriately load the circuit, and distort signals, at higher frequencies. The ZS Series features both high input R (1 MΩ) and low input C (0.9 pF) to reduce circuit Loading across the entire probe/oscilloscope bandwidth. The ZS1000 is ideal for 200–600 MHz oscilloscopes.

Time-Resolved Electrochemical Quartz Crystal Microbalance
400C Series
The quartz crystal microbalance (QCM) is a variant of acoustic wave microsensors that are capable of ultrasensitive mass measurements. Under favorable conditions, a typical QCM can measure a mass change of 0.1-1 ng/cm2. QCM oscillates in a mechanically resonant shear mode under the influence of a high frequency AC electric field which is applied across the thickness of the crystal. Figure 1b below shows an edge view of a QCM crystal undergoing oscillatory shear distortion. The central portions of the top and bottom of the crystal are coated with a typically disk-shaped thin metal film (e.g., gold).
