Congratulations on your purchase of an OA 5000 Series Optical Attenuator. The OA 5000 Series Optical Attenuators are high-performance instruments used to attenuate optical signals. The OA 5000 Series consists of four instru- ments, the OA 5002, OA 5012, OA 5022, and OA 5032. The major difference between the models is the optical fiber connection.

Connect the TM5000 power module to the Interface GPIB using an IEEE Std 488 GPIB cable (available as Tektronix part number 012-0991-00). The TM5000 power module has a 24-pin GPIB connector on its rear panel (Figure 3-1). This connector has a D-type shell and conforms to IEEE Std 488.
Page 49
Setting Up the Instrument GPIB Connector Figure 3-1: GPIB Connector Location GPIB Requirements Observe these rules when using your OA 5000 with a GPIB network: Each device on the bus must be assigned a unique device address; no two devices can share the same device address. Do not connect more than 15 devices to any one bus.
Page 50
Once you have set the address, you can control the OA 5000 through the GPIB interface. 3---3 OA 5000 Series User Manual Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com...

Command Syntax Enter commands in upper or lower case. Command Entry Precede any command with blank characters. Blank characters include any combination of the ASCII control characters 00 through 09 and 0B through 20 hexadecimal (0 through 9 and 11 through 32 decimal). The OA 5000 ignores commands consisting of any combination of blank characters, carriage returns, and line feeds.
