DTA-2115B – All-Standard VHF/UHF/L-Band Modulator for PCIe The DTA-2115B is a high-end modulator with high output level (0dBm) and great phase noise figure. Use the DTA-2115B to generate any QAM signal, or even 8 QAM channels with the new 8-channel firmware. |
 |
DTA-2116 – All-Standard 0-3GHz Modulator for PCIe Successor of the DTA-2115B with a low-profile PCIe form factor, wider programmable output level range and better synchronization capabilities. However, the DTA-2115B supports an 8-channel option, not available for the DTA-2116. |

DTU-315 – All-Standard 0-2GHz Modulator for USB-3 A portable variant of the DTA-2111B: easy to install and easy to carry to demos and around the lab. Like the DTA-2111B, the DTU-315 uses an all-digital modulation and upconversion architecture, with support for L-Band as well. However, as the DTU-315 is bus powered, the DTA-2111B has a better specifications for output level (-9dBm vs -25dBm). |
