Spectrum Analyzers FAQs

Spectrum Analyzers FAQs

General Questions

Spectrum mode allows you to view which frequencies in the spectrum are already in use or have a high noise floor. Selecting a channel with a low reading will yield increased throughput and lower latency.

For specific frequency measurements, use the cursors or the divisions on the screen. To view WiFi channels, click on the plus sign in the top left corner. Then, tap on any of the channel numbers listed. Specific WiFi guides such as 802.11b, 802.11g, 802.11n -20MHz (2.4GHz only), 802.15.4 (ZigBee) can also be enabled. To change the channel map, go to the menu bar and tap Measure. The option at the bottom of the menu is WiFi guide. This will enable you to manually select a guide. The default is 802.11n - 20MHz.

Yes, the app is called WiPry. It easy to install and available free in the Apple App Store

Yes. It is also possible to email the screenshot directly from your device.

The center frequency of the supplied antenna is 2.45GHz.

The gain of the supplied antenna is +1dBi.

Directionality is dictated by the antenna you are using. Our current antenna is omni-directional. If you would like to make directional measurements, a patch antenna should suffice. Unfortunately, we do not currently offer other antennas for sale. You may also need our conducted measurement kit to get the appropriate connector.

Yes! WiPry 2500x is a dual band spectrum analyzer that supports both 2.4 & 5 GHz.

Yes! Our newest product, WiPry Clarity, supports Wi-Fi 6/6E as well as all legacy Wi-Fi technologies (2.4 & 5 GHz).

WiPry Clarity Questions

No, WiPry Clarity draws current from the host device. No batteries are required.

WiPry Clarity supports PC. Mac is currently in process. And Linux is in the roadmap. In the past, Oscium products have supported all platforms (including iOS & Android) but mobile platforms limit performance (because there is a limited amount of power supplied). So, for WiPry Clarity, we have excluded iOS and Android to achieve the full spectrum view that Wi-Fi 6/6E require. We are working on ways to expand Wi-Fi 6/6E features into mobile.

If portability is critical, Oscium does offer the WiPry 2500x. It's a dual band spectrum analyzer (2.4 & 5 GHz) with cross platform support (iOS, Android, PC, Mac).

No. The Oscium supplied software for WiPry Clarity is free.

WiPry-Pro Questions

If you're using an iPhone / iPod touch, you can use WiPry-Pro continuously for approximately five hours.

If you're using an iPad, you can use WiPry-Pro continuously for approximately eight hours.

Please understand that these estimates are just that, estimates. Your results may vary based on your background usage level (WiFi, email push, other apps, etc).

In the past, SSID functionality has been available to iOS users but not in accordance with Apple guidelines. It was then restricted and only available in a jailbroken store. We comply with every requirement so our customers can be confident that our features are here to stay. The more technical answer is that our external WiFi chip (that one that provides SSID's) uses more than 100mA so we have to add a super cap to make sure we stay under the 100mA power threshold set by Apple. The upside to the user is that the battery does not drain as fast and the functionality is here to stay. The downside is that you have to wait two minutes for the first SSID scan. If you're annoyed by the amount of time it takes to do the first scan, we have eliminated the wait time entirely in our newest hardware, WiPry 5x. Please consider upgrading your hardware.

200ms or 5fps. The 20s referesh rate is only on the SSID beacon capture. No need to worry about missing bluetooth scans, for example. 200ms or 5fps is sufficient to capture relevant signals.

WiPry-Pro Combo Questions

If you're using an iPhone / iPod touch, you can use WiPry-Pro Combo continuously for approximately five hours.

If you're using an iPad, you can use WiPry-Pro Combo continuously for approximately eight hours.

Please understand that these estimates are just that, estimates. Your results may vary based on your background usage level (WiFi, email push, other apps, etc).

Explain why the power meter mode of WiPry-Pro Combo is useful.

Most power meters can only provide you with an average power reading. Very few are capable of measuring peak power. Oscium's power meter will allow you to visually look at protocol-level transmissions, duty cycles, and more. This invaluable tool makes protocol verification and troubleshooting wireless devices easier than ever.

Max power is 20dBm. If you need to take higher power measurements, please make sure that you use external attenuation to bring the power level below 20dBm.

External attenuation allows you to apply an offset (either gain or attenuation) to bring the measurement into range.

You will need the conducted measurement kit even if you plan to make radiated measurements.

Oscium does not stock attenuators but they are readily available in the marketplace.

We will make attenuators in the future if the demand is sufficient. Please email us if you are interested.

The spectrum analyzer sweep time is 200ms or 5fps. The 20s refresh rate is only on the SSID beacon capture. No need to worry about missing Bluetooth scans, for example. 200ms or 5fps is sufficient to capture relevant signals. On the power meter, it can trigger on amplitudes so you could capture signals at speeds up to 50MSPS.

Rows

When the time scale is set to less than 100ms, each row is a single screen capture. When the time scale is greater than or equal to 100ms, each row is a data point in time.

Columns

Each column (excluding the first) is the data point in time shown on the screen.
