Preface
This instruction manual describes the GPIB and USB interfaces of WF1947/WF1948. For operations
from the panel, see the separate manual "WF1947/WF1948 Instruction Manual (Operations)."
The GPIB and USB interfaces of WF1947/WF1948 features abundant functions and can control
almost all operations on the front panel. In addition, they can read the setting values from external
equipment such as PC.
WF1947/WF1948 Instruction Manual (External Control) consists of the following chapters.
1. Preparations before Use
This chapter describes the interface settings and the GPIB address settings.
2. Command Descriptions
This chapter describes the overview of the commands and setting examples.
3. Status System
This chapter describes the status reporting, including status byte, and standard event status
register.
4. Error Message
This chapter describes the error numbers and their meaning.
5. Specifications
This chapter describes the specifications of the external control interfaces.
6. Compatibility of External Control
This chapter describes the differences of control methods and the commands to which you
need to pay attention when migrating from our other WAVE FACTORY series products to
WF1947/WF1948.
