Connecting a Signal Using a TekConnect Probe

You can connect a signal to the analyzer using a TekConnect Probe by using an RTPA2A Real-Time
Spectrum Analyzer TekConnect Probe Adapter. The RTPA2A enables you to use Tektronix P7000 Series
active and differential probes to connect to signals. See the RTPA2A Instruction Manual for instructions
on how to connect the probe adapter and a probe to the analyzer.
Installing the RTPA2A Probe Adapter Device Driver
When the RTPA2A probe adapter is connected to the instrument's USB port for the first time, the Windows
Add Hardware wizard may automatically start. If the wizard does start, use the procedure below to install
the device driver for the new hardware. (If the wizard does not start, the probe adapter device driver is
already installed.)
To properly install the probe adapter device driver:
1. Select the option for Windows to install from a specific location (then select Next).
2. Only search for the driver in the following location depending on your instrument:
C: \Program Files\Tektronix\SPECMON\RSA\ProbeAdapter
3. If Windows warns about Windows Logo testing, select Continue Anyway.
4. Select Finish after the Found New Hardware wizard completes.

Connecting External Trigger Signals

External trigger signals are connected to the analyzer using the Trig In connector on the front panel. There
is also an additional trigger input on the rear panel, the Trig 2 In.
To connect a trigger signal to the analyzer, connect the signal to the Trig In connector on the front panel,
or the Trig 2 In connector on the rear panel.
