The Tektronix 2754P is a spectrum analyzer with a frequency range of 10 kHz to 21 GHz. The P suffix designation indicates GPIB Programmability. The minimum resolution bandwidth is 1 kHz, and provides measurement resolution proportional to the frequency accuracy or span. In addition to conventional digital storage features, non-volatile memory (NVRAM) stores up to 9 separate waveforms with their readouts and markers, for later recall for additional analysis and comparison, and 10 control settings. Also, store up to 39 preselector peaks and 12 external band peaks. The instrument can selectively count one particular signal out of several that may be present at its input.

The single and delta markers provide direct readout of frequency and amplitude information of any point along any displayed trace. Or, get the relative (delta) frequency and amplitude information between any two points along any displayed trace or between traces.

Additional features include: Continuous Resolution Frequency Tuning, Up to 80 dB Viewable Dynamic Range, Built-in Frequency Counters Provide Frequency Determination to within 0.0000001%, Sensitivities to -134 dBm, Built-in Intelligence for Signal Processing/Marker Functions, Push Button Occupied-Bandwidth/Noise Normalization Functions, Macro Capability with Nonvolatile Memory, Optional Switch-Selectable 50/75Ω Impedances, Direct Screen Data Plots without a Controller, and optional MATE/CIIL Compatibility for Military Applications.

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); and Camera Power .

Rear panel inputs/outputs are: PROBE POWER (Provides operating voltages (+5 V, -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 (EXT IN) BNC connector (Interfaces to a Tektronix 1405 TV Adapter to display an externally-generated marker); EXT REF IN BNC connector (A 50Ω input for a 1, 2, 5, or 10 MHz external reference signal; 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, 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 female DB25 connector (Provides bidirectional access to the instrument bus)); IEEE STD 488 PORT GPIB interface.
