Getting Started Manual

TRIG/SWEEP OUT

The TRIG/SWEEP output socket provides both trigger and marker signals, depending on the instrument's mode of operation.

Its primary use is for triggering an oscilloscope or other recording device, but it can also provide z-axis bright-up markers during sweep and frequency-hopping modes.

RS232 and GPIB Interface Connectors
These sockets are for
controlling the instrument
remotely, using a PC or
other controller device.
Remote control is beyond
the scope of this Getting
Started Manual, but is
covered in detail in chapter
16 of the Users Manual.	shx0017f.gif
