4400-8-31/5

Spectrum Control's Weinschel’s 4 Channel Programmable Attenuators are 50 ohm bidirectional units that operate over the 0.1 to 8 GHz frequency range. Model 4400-8-31/5 offers an attenuation range of 0 to 31.5 dB in 0.5 dB step size. These units can be controlled using USB and Ethernet interfaces. The AUX connector provides a logic-level SYNC output signal that is pulsed high for 100 usec whenever an attenuation value is changed. A Programmable TTL trigger is available through the AUX port.
