octoBox® quadAtten module contains 4 individually programmable RF attenuators. quadAtten offers the best RF isolation on the market, making it suitable for controlled octoBox wireless testbed environment. With its high power handling, quadAtten can be directly connected to an antenna port of a device while maintaining signal linearity.
- See more detail in the quadAtten datasheet (PDF)
Applications
- Wi-Fi up to 6e and cellular (GSM, UMTS, LTE, FDD, TD-LTE and LTE-Advanced) testing
- Throughput vs. range measurements when used with the octoBox testbed
- RX sensitivity measurements
octoBox quadAtten is an exceptionally well isolated with filtered USB and Ethernet interfaces.

Attenuator Programming
QuadAttenuatorControl command line parameters
| Example | Description | |
|---|---|---|
| -d | -d COM11 -d QuadName -d 192.168.15.56 -d QA40516-02 |
Selects the device to use either the com port, name, IP address, or serial number. If –d is not specified will look for a QuadAtten that is connected via USB. |
| -c | -a 14.5 –c 1 | Specifies the channel to set. |
| -a | -a 14.5 -a 14.5 –c 1 |
Sets the attenuation value. If no channel is specified 1 will set all channels equal to this value. |
| -i | -i 192.168.15.56 | Sets the IP address of the device. |
| -g | -g 192.168.15.1 | Sets the Gateway address of the device. |
| -s | -s 255.255.255.0 | Sets the subnet mask of the device. |
| -n | -n SignalAtten1 | Sets a custom name used to help identify and address multiple quadAttens. (Max 20 characters no spaces) |
| -z | -z | Returns information settings of the device. (Name, serial, firmware, IP address, subnet, gateway, MAC address, Ch1/2/3/4 settings) |
