The '''Tektronix 496''' is a spectrum analyzer with a frequency range of 1 kHz to 1.8 GHz. The '''P''' suffix designation indicates GPIB '''P'''rogrammability. The minimum resolution bandwidth is 30 Hz, and provides measurement resolution proportional to the frequency accuracy or span. With non-volatile memory (NVRAM) you can save up to 9 waveform displays, up to 10 complete front panel measurement parameter setups, and 8 K for programming macros of commonly used routines. | The '''Tektronix 496''' is a spectrum analyzer with a frequency range of 1 kHz to 1.8 GHz.

PEN LIFT (OUTPUT) [[BNC connector]] (Provides access to a TTL compatible signal to lift the pen of a chart recorder during sweep retrace. This signal is always derived from the spectrum analyzer sweep. In Opt. 42 instruments, 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); EXT REF IN [[BNC connector]] (A 50Ω input for a 1, 2, 5, or 10 MHz external reference signals, within -15 dBm to +15 dBm level. Input signals must be a sinewave with a duty cycle symmetry of 40% to 60%, or ECL or TTL); J104 ACCESSORY (B053575 AND UP) female [[DB25 connector]] (Provides bidirectional access to the instrument bus. For instruments B053574 and below, this connector has no application.); IEEE STD 488 PORT [[GPIB interface]] (Added to all "P" suffixed instruments) | PEN LIFT (OUTPUT) [[BNC connector]] (Provides access to a TTL compatible signal to lift the pen of a chart recorder during sweep retrace.
