- Typical interval: 12 months is common in RF/microwave labs for attenuators used in measurement chains.
- Depending on usage and criticality, intervals may range from 12 to 24 months. High-use, high-power, or harsh-environment applications should stay at 12 months or shorter. If used as a working standard, keep at 12 months.

Keysight (Agilent/Hp) 33321H Calibration
Your Keysight (Agilent/Hp) 33321H Doesn’t Need Guesswork.
It Needs Calibration — Without the Runaround.
Your organization trusts the Keysight (Agilent/HP) 33321H Programmable Step Attenuator, 70 dB to tell you the truth.
So why accept a calibration sourcing process built on phone tag, vague quotes, and one‑size‑fits‑all labs?

Our partners provide traceable electrical calibration services to help ensure measurement accuracy, compliance, and continued usability of your equipment.
Quick Overview
What it is: - A 50 Ω programmable step attenuator module providing 0–70 dB in 10 dB steps (electromechanical relay/absorptive design)- Typical use: - OEM/input attenuator in RF instruments; bench/test-system level setting; amplitude range extension and protection in DC-to-microwave paths- Status: - Obsolete (out of production, no longer supported by the OEM; available used/refurbished as a spare part)A Keysight (Agilent/HP) 33321H Programmable Step Attenuator, 70 dB doesn’t lie—but it will expose lazy calibration. High‑accuracy measurements demand calibration performed by technicians who understand the 33321H, the specification limits, and the standards behind them.
Expert calibration verifies performance against traceable references, flags drift before it becomes failure and documents every adjustment. This isn’t box‑checking or sticker‑slapping. Its precision enforced. If your work depends on numbers you can defend, Rogue Calibration helps find the right calibration service provider for you.
