This Anritsu calibration guide provides performance verification procedures, specifications, and recommended test equipment for OSL Series precision…
The guide explains how to verify the performance of Anritsu OSL Series precision open/short/load calibration tees. It includes safety symbols, warranty information, and a description of the different models in the series.
The document contains recommended test equipment, detailed specifications, and step‑by‑step verification procedures such as return‑loss and load‑resistance checks. Tables list the frequency range, load resistance tolerance, return‑loss values and phase‑shift accuracy for each model.
| Frequency Range (OSLN50LF) | DC to 4 GHz |
|---|---|
| Load DC Resistance | 50 ± 0.25 Ω |
| Return Loss | 42 dB (DC‑5 GHz), 36 dB (5‑15 GHz), 32 dB (15‑18 GHz) |
| Open and Short Phase Shift | 180° ± 6° (4 GHz), ±10° (6 GHz), ±20° (18 GHz) |
Anritsu recommends a Vector Network Analyzer such as Model 37247D or 37347D (40 MHz‑20 GHz) and the Anritsu SC6650 adapter, among other equipment.
The OSLN50LF model operates from DC up to 4 GHz.
The load DC resistance must be 50 Ω with a tolerance of ±0.25 Ω.
