  Welcome to our collection of guides and how-tos covering industry-related topics beyond SoundBase.
  - Touring with Coord
    Coord offers a simple workflow for organizing tours, where each Site acts as a tour stop.
  - Avoiding house frequencies
    House frequencies can be defined as any frequency that is already transmitting in a venue that you are going to be working in.
  - Manually analyze incompatible frequencies
    Coord automatically inspects and analyzes frequencies whenever inclusions, exclusions, and calculation settings are changed across frequencies, groups, zones, and sites.
  - Managing outside productions’ frequencies in a venue
    There are many ways to handle sharing the information from a venue’s existing devices to an incoming production.
  - Exporting/importing frequencies from Coord to Wireless Workbench
    You can export your created zone and import it into your site later.
  - Exporting/importing frequencies from Coord to Sennheiser Wireless Systems Manager
    You can export your created zone and import it into your site later.
  - Importing and managing custom equipment profiles
    SoundBase has the capability to import various types of equipment profiles. These profiles include SoundBase, Wireless Workbench, and IAS.
  - Modifying report templates
    Coord Reports are generated using a service provided by Carbone.io. When you run a report on SoundBase, it sends a JSON object with the Project’s info to the Carbone.io API which renders the selected template.
  - Clearing SoundBase Pro local database
    Your database can be easily cleared when using local data on your computer.
  - Update TinySA firmware on a Mac
    This guide explains how to update the firmware on a TinySA device using a Mac computer. The process involves installing software tools, downloading firmware files, and using terminal commands to complete the update.

Collecting high-quality scan files with tinySA

This guide walks you through using a tinySA Ultra or tinySA device to collect UHF spectrum scans suitable for wireless frequency coordination in SoundBase.

What is required:

A tinySA Ultra (recommended for higher resolution: 450 points per scan)
A tinySA (supports fewer points; see notes below)
An antenna connected and in free space (away from metal surfaces or shielding)
An SD card inserted and formatted (FAT32)

Target Frequency Range

To support wireless mic and IEM planning, we focus on 470 MHz to 636 MHz(UHF TV Band).

With 25 kHz spacing, this range requires ~6,640 data points. The tinySA Ultra supports 450 points per scan, so split into 15 scans:


Scan #	Start – End (MHz)	Center Freq (MHz)
1	470.000 – 481.250	475.625
2	481.250 – 492.500	486.875
3	492.500 – 503.750	498.125
4	503.750 – 515.000	509.375
5	515.000 – 526.250	520.625
6	526.250 – 537.500	531.875
7	537.500 – 548.750	543.125
8	548.750 – 560.000	554.375
9	560.000 – 571.250	565.625
10	571.250 – 582.500	576.875
11	582.500 – 593.750	588.125
12	593.750 – 605.000	599.375
13	605.000 – 616.250	610.625
14	616.250 – 627.500	621.875
15	627.500 – 638.750	633.125

If using a standard tinySA, reduce span to ~7 MHz per scan to maintain the same resolution due to lower point limits.

Recommended tinySA Settings:


Setting	Value
Span	11.25 MHz
RBW	100 kHz
Step Size	25 kHz (automatically derived)
Sweep Mode	Normal or Average
Averages	Optional: 3–5 if noisy
Reference Level	Adjust so peaks are visible

To save each scan:

Tap Storage.
Tap Save Capture.
Rename the file to match the range, like Scan_470-481.csv
Confirm it saved to the SD card.
Repeat this for each scan step.

You have successfully collected high-quality scan files with tinySA.
