Attenuator vs Gilson Guardian
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Attenuator
Calculate output voltage, power, and attenuation based on input values and dB of attenuation. Features NMR-specific calculations for pulses and measures local magnetic fields and barometric pressure.
- Calculate output voltage and power
- Specify input voltage (Vpp or Vrms)
- Calculate attenuation in dB
- NMR pulse calculations
- Measure local magnetic field
- Display barometric pressure

Attenuator is a utility for anyone working with radio frequency sources and needs to know power and voltage after attenuation. You can specify an input voltage (Vpp or Vrms) and dB of attenuation to get the output voltage, power and attenuation. The impedance can be specified, typically 50Ω for most systems. There is a new emphasis on NMR utility, with options for calculating pulses based on reference power and pulse length. Powers are in Watts, dBm, and dB values. Measure local magnetic field to check stray static fields from magnets. See the local barometric pressure, useful if the magnet boil-off is high

MOBILE APP FOR END-TO-END CMT WORKFLOW The Guardian mobile app is used by field technicians to track sample and site data from the field to the lab and beyond, ensuring complete chain-of-custody for all project stakeholders. SURETY STARTS IN THE FIELD Capture, claim and locate sample data and sync information to the lab. CAPTURE When a new batch of concrete arrives on site, field technicians can capture sample data and create new specimens. -Input sample ID, ticket number, placement, date and wet concrete information directly in app without connectivity. -Automatically sync data with the Guardian database. -Access this data to inform future steps in the construction materials testing workflow. CLAIM Drive accountability on the job site for managers and field technicians by claiming specimens. -Filter samples in the app by sample ID, project ID, location, sample data and status. -Assign chain of custody status to each sample’s specimens: Cast, Assigned, Claimed, Collected and Delivered. -Claim a sample’s specimens that have not yet been received at the lab or assign someone else to pick up the specimens. LOCATE When assigned to pick up a sample’s specimens, the field technician can view a map with pins that show the exact location of specimens on the job site. -Proactively pick up unclaimed specimens that are ready to move to the lab. -Help new technicians or technicians who haven’t been to the job site find the specimens they need to pick up. -Prevent unclaimed specimens from sitting onsite too long and eliminate penalties for improper curing or late or missing tests. FOR GUARDIAN USERS The Guardian mobile app is a powerful tool for field technicians, lab and project managers, and principal engineers who subscribe to the Guardian software program and use our LIMS as their essential concrete testing software. VALIDATE LAB TESTING AGAINST FIELD WORK -Trust materials meet your project’s standards -Streamline complex workflows for greater productivity and profitability. -Fully close the data gap between key stakeholders and steps of the CMT workflow. -Avoid miscommunication and discrepancies as data moves from the field, to the lab, to the office and beyond.

Verdict
The clearest difference is in-app purchases: Gilson Guardian at none against Attenuator's 1. Gilson Guardian also leads on device support (3 vs 1) and iOS requirement (13.0 vs 17.6). On price and ads there is nothing between them.
