## Most critical reviews (5 lowest-rated)

### 1/5 — Does not work anymore Sep2025

*2025-09-26, version 3.0*

This calculator has stopped working and exits as soon as you try to activate a calculation.

### 1/5 — Incorrect calculations

*2024-10-17, version 3.0*

Wrong calculations for mismatch loss and RL.

### 2/5 — Glaring deficiencies

*2015-01-30, version 3.0*

This appears to be a remake of the old Agilent calculator, which, though incomplete, was a cool and functional device. This new Keysight calculator, however, confuses return loss with insertion loss and vice versa. It also displays the decibel (dB) as a non-absolute term, which is a gross error. You need to clean this thing up.

### 4/5 — Nice replacement for slide rule

*2014-06-23, version 2.1*

For those familiar with using the old HP reflectometer calculator, this is a nice substitute. You can do most things that you usually do with the slide rule. It's a little easier to carry around than the slide rule, too. My suggestion is to compare the app with your slide rule until you're familiar with what function corresponds to your slide rule. Well done.

### 5/5 — Awesome

*2010-05-11, version 0*

Don't need cardboard slider version anymore!
