OA 5000 Series User Manual 2 --- 5 Setting Attenuation Levels Because the OA 5000 automati cally adjusts the attenuator to co rrect for different wavelengths, i t is impo rtant, for attenuator accuracy , to co rrectly match the display ed w avelength with the wavelength of the si gnal go ing i nto the unit.
Setting Attenuation Levels User Reference 2 --- 6 Step 2: Use the two knobs to adjust the displ ayed wavelength val ue. The COAR SE k nob changes the displ ayed val ue by 10 nm per cl ick and the FINE knob changes the display ed value by 1 nm per cli ck.
Setting Attenuation Levels OA 5000 Series User Manual 2 --- 7 T o set the attenuation level to minimum, press the MIN A TT button. Setting the attenuatio n to minimum sets the absol ute attenuatio n to 0 dB. This means that the OA 5000 i s not attenuating the opti cal i nput.

OA 5000 Series User Manual 3 --- 5 Co mmand Syntax Y ou can contro l the OA 5000 through the GPIB usi ng a large gro up of co m- mands and queries. This sectio n describes the syntax these commands and queries use and the conventi ons the OA 5000 uses to process them.
Com man d Syntax Pr og ra mming 3 --- 6 Commands consi st of set commands and query commands (usual ly simply called co mmands and queries). Commands modify i nstrument settings or tell the O A 5000 to take a specific action. Queri es cause the OA 5000 to return informati on about its status.
Com man d Syntax OA 5000 Series User Manual 3 --- 7 Commands Commands cause the OA 5000 to perform a specifi c functio n or change o ne of its setti ngs. Commands have the structure: H [:]<Header>[<Space><Argument>[<Separator><Argu- ment>].
Com man d Syntax Pr og ra mming 3 --- 8 H Enter commands in upper o r lower case. H Precede any co mmand w ith blank characters. Blank characters include any combi nation of the ASCII contro l characters 00 through 09 and 0B through 20 hexadecimal (0 through 9 and 11 through 32 deci mal).
Com man d Syntax OA 5000 Series User Manual 3 --- 9 is a vali d message that sets the attenuation to 15 dB, the displ ay mo de to dB, and responds with the disabl e status and the adj usting status. Concatenated commands and queri es are executed in the order re- ceived.
