The Tektronix 2782 is a spectrum analyzer with a frequency range of 100 Hz to 33 GHz in coax, to 325 GHz with external waveguide mixers. The minimum resolution bandwidth is 3 Hz, with a minimum span of 10 Hz, 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 20 separate waveforms with their readouts and markers, for later recall for additional analysis and comparison.
Also, store up to 20 different front-panel control setups for future recall. 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.
The additional major performance features of this instrument include: low phase noise, two user-assignable knobs, synthesizer frequency accuracy, remote operation over GPIB, precision signal counting, single and delta marker modes, precise amplitude measurement, digital storage and real time display, user-defined key sequences and macros, multiband sweep, front-panel keypad for data entry, three-color display, on-screen text entry, strong front end, full screen plot, menu-driven user interface, and dedicated function keys for commonly-performed tasks.
Front panel inputs/outputs are: RF INPUT 50Ω Planar Crown connector (Compatible with K or type N connectors); EXTERNAL MIXER SMA connector (50Ω) , LO OUTPUT SMA connector (Provides access to the output of the 1st local oscillator at >+4 dBm. Must be terminated in 50Ω at all times); REF SIGNAL OUT SMA connector (100 MHz -20dBm phase locked to reference oscillator); and ACCESSORY IN (general purpose serial data port); PROBE POWER (Provides operating voltages for active probes).
Rear panel inputs are: FREQ REF (IN/OUT) BNC connector (50Ω; Input signal freq. allowed: 10 MHz ±5 Hz, Input signal amplitude range: 0 dBm to +15 dBm max; Output signal: Nominally 0 dBm at 10 MHz (TTL-compatible), Phase noise allowed: ≤-100 dBc/Hz at 1 Hz offset); TRIG/HORIZ IN BNC connector (Nom 1 kΩ, or 8.25 kΩ (sweep mode), Input voltage change for triggering: 0.5V P-P, Input voltage for sweep: selectable between 0 V left side to +10 V right side of screen, between -5 V left side to +5 V right side of screen)); ACCESSORY female DB15 connector (External inputs and outputs); and INSTRUMENT BUS female DB9 connector (Serial communications bus that processors use to communicate with each other and rest of instrument modules).
Rear panel outputs are: V OUT BNC connector (50Ω; External display vertical signal output); H OUT BNC connector (50Ω; External display horizontal signal output); Z OUT BNC connector (50Ω; External display blanking signal output); IF OUT BNC connector (50Ω; Amplitude); and PORT 1 GPIB interface and PORT 2 GPIB interface.
