Agilent 82357B USB/GPIB Interface User’s Guide 2 Using the Agilent 82357B This chapter describes normal operating states and modes for the 82357B and provides the guidelines to use the 82357B, including: • Initial 82357B operating states • Introduction to 82357B operating modes • Single 82357B operation • Multiple 82357B operation • SRQ operation Agilent Technologies 17
2 Using the Agilent 82357B Initial 82357B Operating States Figure 2- 1 shows the sequence of initial operating states when the 82357B is first connected to a USB port on a PC or on a USB hub.
Using the Agilent 82357B 2 Introduction to 82357B operating modes The 82357B has two modes of operation. When only one 82357B is connected to a USB port within a system, we define the feature as the Single Mode Features. When up to four 82357Bs are connected at the same time to USB ports within a system, we define the feature as the Multiple Mode Features.
2 Using the Agilent 82357B Single 82357B operation When an 82357B is first installed, a default VISA Interface ID, SICL Interface ID, Logical Unit (LU) number and GPIB Address are automatically assigned to the serial number associated with this specific 82357B. For example, assume an 82357B with serial number MY12345678.
Using the Agilent 82357B 2 If you disconnect this 82357B and plug in another 82357B (with a different serial number), or if you re- plug the same 82357B, the new 82357B will assume the same VISA Interface ID, SICL Interface ID, LU number, and GPIB Address as the previous 82357B. Multiple 82357B operation When two or more 82357Bs are attached to a system at the same time, we define the mode as the multiple mode of operation.
2 Using the Agilent 82357B NOTE • You can change the parameter values of the 82357B as required. See “Changing configuration parameters” on page 23 for details. • You can also convert from multiple mode operation to single mode operation. See “Changing modes of operation” on page 24 for details.
Using the Agilent 82357B 2 Setting Configuration Parameters This section gives guidelines to change or set various configuration parameters for the 82357B, including: • Changing Configuration Parameters • Changing Modes of Operation • Setting Timeout Floor Value • Setting High- Performance Operation Changing configuration parameters To change the VISA or SICL Interface ID, the LU or GPIB Address, or if you want to check the values of these configuration parameters, highlight the USB/GPIB interface in the
2 Using the Agilent 82357B Figure 2-2 Agilent 82357B (High Speed) Interface - USB/GPIB Changing modes of operation If your system has multiple 82357Bs configured (multiple mode operation), the only way to change from multiple mode of operation to single mode operation is to perform the following: 1 Unplug all 82357Bs from the system. 2 Run Connection Expert (click the IO icon, then click Agilent Connection Expert).
Using the Agilent 82357B 2 Setting timeout floor values The 82357B has a default timeout “floor” value that is an internal requirement to ensure reliable USB communication. The 82357B will not allow timeouts less than the floor value. (By default, VISA/SICL timeouts are set to infinite time). To programmatically determine the timeout floor, you can set the timeout to a very small value, such as 1 ms, then query for the actual timeout floor value.
2 Using the Agilent 82357B Setting 82357B high-performance operation NOTE Changing the T1 delay as described in this section is an advanced feature and also requires attention to cable lengths and other system features. Introduction The GPIB transfer rate for 82357B writes using large (>1000 bytes) buffer size is affected by the Data Available (T1) delay time. (The transfer rates are not noticeably affected when the buffer size is <1000 bytes). The default delay time used by the 82357B is 800 ns.
