Front panel inputs/outputs are: RF INPUT 50Ω [[N connector]] (Input connector for RF signals to 21 GHz. If input signal has a dc component use a blocking capacitor in line with the signals); CAL OUT [[BNC connector]] (Calibrator output provides -20 dBm 100 MHz signal and a comb of frequency markers 100 MHz apart); 1ST LO OUTPUT [[SMA connector]] (Provides access to the output of the 1st local oscillator. Must be terminated into 50 Ω when they are not connector to an external device); 2ND LO OUTPUT [[SMA connector]] (Provides access to the output of the 2nd local oscillator. Must be terminated into 50 Ω when they are not connector to an external device); EXTERNAL MIXER RF INPUT [[TNC connector]] (50Ω); and Camera Power . | Front panel inputs/outputs are: RF INPUT 50Ω [[N connector]] (Input connector for RF signals to 21 GHz.

Rear panel inputs/outputs are: PROBE POWER (Provides operating voltages (+5V, -15 V, +15 V; 100 mA max each) for active probes); HORIZ|TRIG (EXT IN) [[BNC connector]] (A dual function connector: When in External Triggering mode the connector is an AC coupled input for trigger signals. When the TIME/DIV selection is EXT the connector is a DC coupled input for horizontal sweep voltages); MARKER/VIDEO (OUTPUT) (B053575 AND UP) or EXT PRESELECTOR (OUTPUT) (B053574 and below) [[BNC connector]] (MARKER/VIDEO interfaces the 492/492P with a TV Sideband Adapter, such as the Tek 1405, so a marker from the adapter is displayed on the internal video. External video applied to this connector will also be displayed if pin 1 of the ACCESSORIES connector is grounded. EXT PRESELECTOR provides a variable voltage (approx -0.2 V to +10 V) that is proportional to center frequency, for preselector bands of Opt. 01 instruments, to drive an external preselector.); Opt. 42 replaces MARKER/VIDEO (OUTPUT) with 110 MHz IF (OUTPUT) [[BNC connector]] (Provides 3 dB signal bandwidth ≥ 4.5 MHz); HORIZ (OUTPUT) [[BNC connector]] (Supplies a 0.5 V/div horizontal signal); VERT (OUTPUT) [[BNC connector]] (Provides access to the video signal with 0.5 V for each division of displayed video above or below the center line.); PEN LIFT (OUTPUT) [[BNC connector]] (Provides access to a TTL compatible signal to lift the pen of a chart recorder during sweep retrace. In Opt. 42 instruments this port may also be used for inputting external video, if pin 1 of the ACCESSORIES connector is ground); use this connector to input external video signals if pin 1 of the ACCESSORIES connector is grounded); 10 MHz IF (OUTPUT) [[BNC connector]] (Provides access to the output of the 10 MHz IF); J104 ACCESSORY (B053575 AND UP) female [[DB25 connector]] (Provides bidirectional access to the instrument bus.
