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?

Rogue Calibration flips that model.

We don’t calibrate your equipment.
We put calibration providers in competition for your business.

What That Means for You

  • Access to calibration labs experienced with Keysight (Agilent/Hp) instruments
  • Accredited and traceable calibration options
  • Documentation suitable for ISO, FDA, and regulated environments
  • Clear turnaround times and transparent pricing
  • Control to choose the provider that fits your needs and timeline

Whether you’re managing a single Keysight (Agilent/Hp) 33321H calibration or coordinating  multiple instruments and locations, Rogue Calibration helps you eliminate guesswork, reduce downtime, and source calibration with confidence.

Better options. Better data. Better calibration sourcing.

Our partners provide traceable electrical calibration services to help ensure measurement accuracy, compliance, and continued usability of your equipment.

Keysight (Agilent/HP) 33321H Programmable Step Attenuator, 70 dB Calibration

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.

FAQ



- 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.



- Time-based: It has reached its calibration due date/interval per your quality system.

- Performance-based indicators:
- Measured attenuation steps (e.g., 10 dB increments) no longer meet expected accuracy across frequency during a verification check.
- Instrument amplitude accuracy or level linearity drifts outside tolerance when this attenuator is in-line (e.g., spectrum analyzer reference level/attenuator checks fail).
- Notable changes in frequency response or increased insertion loss in the “0 dB” path versus historical data.
- After events such as over-power, ESD, shock/vibration, repair/replacement, or exposure to temperature/humidity extremes.

- If integrated into an instrument, built-in self-tests, alignment routines, or amplitude verification failures are also cues to recalibrate or verify the attenuator.
