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]]. | |||
