This chapter describes the features of the Tektronix 2706 RF Preselector and

what you need to use it.

This section presents a brief tour of the Preselector controls and connectors.

The Preselector front panel has the following controls:

H POWER switch – this turns instrument operating power on (1) or off (0).

H REMOTE/LOCAL switch – this transfers control of the Preselector from

remote (GPIB controlled) mode to local (manually controlled) mode. The

REMOTE LED lights when remote mode is selected.

H BYPASS switch – this disconnects all Preselector filters so that the entire RF

signal is sent directly to the spectrum analyzer. The BYPASS LED lights

when bypass mode is selected.

H BAND SELECT <- and -> switches – these select the signal routing band from

among 7 bandpass filters and a high-pass filter. An LED lights on the front

panel to indicate the selected filter.

H RF INPUT – this connects the Preselector to the signal source using a type N

plug.

H RF OUTPUT – this connects the preselected output to the spectrum analyzer

using a type N plug.
