8003 Precision Scalar Network Analyzer

Wide Dynamic Range

The Model 8003 Precision Scalar Network Analyzer can make accurate, single sensor power measurements over a frequency range of 10 MHz to 40 GHz with a dynamic range of –70 to +20 dBm.

This wide dynamic range results from our unique use of switched linear gain stages, with a maximum gain of more than 100 dB,

rather than the log ampliers typically used in other scalar analyzers. In addion to wide dynamic range, our approach also

delivers extremely accurate low level measurements all the way down to –70 dBm.

Power Meter Linearity

The Model 8003 also incorporates a unique, built-in power sweep calibrator that linearizes the sensor’s diode response in

the non-square-law region, from –30 to +20 dBm. The calibraon

system uses the inherent linearity and stability of an ovenized thermistor to accurately calibrate the high-speed diode sensors

from 0°C to 50°C. The result is a linearity specicaon of ± 0.02 dB (0.5%) over any 20 dB span and ± 0.04 dB (1%) over the enre 90 dB dynamic range to ensure accurate rao or relave

measurements.

Absolute Power Measurements

The same built-in calibrator that linearizes the sensor provides a

1 mW signal accurate to within ±0.7%, stable over temperature and me, and traceable to NIST. Each Giga tronics power sensor contains an EEPROM programmed with the frequency calibraon

factors measured at the factory, or in your Cal Lab. When you key in the frequency at which power is being measured, the

meter automacally applies the correct calibraon factor from the sensor EEPROM.

The combinaon of an accurate, traceable calibraon reference

and an accurate frequency response curve for each power sensor ensures absolute power measurements with power meter accuracy.

Power Sensors to meet your Applicaon

Giga-tronics oers an extensive line of power sensors for

the Model 8003 to address a variety of power measurement

applicaons. This includes standard CW power sensors, low

VSWR CW power sensors, true RMS sensors, and our unique triggerable pulse sensors.

The 80340 Series triggerable pulse sensors let you display the response from a pulsed source. You can choose between

two modes of operaon - measure with either a pulsed xed

frequency (CW mode), or with a pulsed swept frequency (start/ stop mode) signal from a sweeper (swept signal generator). The sensors can also be used to display the response of devices with

no pulse modulaon on the signal generator.

Averaging: 2, 4, 8, 16, 32, 64, 128, or 256 successive traces

(swept) or readings (CW) can be averaged to reduce eects of

noise on measurement.

non-volale memory and normalized with the highest resoluon, independent of display scale/division or oset. Up to 4,096

points for each trace are stored over the full frequency range of

the sweeper or any user selected frequency range. Normalizaon data is automacally interpolated for ranges within the original

normalized range.

Sengs Store/Recall: Allows up to nine front panel setups, plus a power down last instrument state, to be stored and recalled

from non-volale memory.

non-volale memory. Complex limit lines can be entered through

the front panel or via GPIB interface.

cursor on all acve channels is digitally displayed.

Cursor Delta: Displays dierences in dB and frequency between the reference cursor and the main cursor.

Cursor Min/Max: Automacally moves the cursor to the minimum or maximum value of test data.

Cursor “x” dB: Automacally moves the cursor to the point on the trace equal to the value of “x” in dB or dBm.

Cursor “x” Bandwidth: Automacally displays cursors right and le of the cursor at the frequencies where the test data is equal to

the value of “x” dB, and displays the bandwidth between the cursors.

Ref to Cursor: Automacally changes the Ref Level to the level at the cursor.

Markers: Displays up to 10 markers generated by the 8003. The cursor can be moved directly to any marker or moved sequenally

through the markers.

Accuracy

Transmission Loss or Gain Measurement: Transmission loss or gain measurements are made relave to a 0 dB reference point established during calibraon. Therefore, frequency response errors of the source, sensors, and signal spling device are removed.

The remaining elements of uncertainty are mismatch error, instrument linearity (Fig. 1) and noise uncertainty given in the absolute

power accuracy secon.

35142-Rev.A/ US032012

Transmission Accuracy = Instrument Accuracy + Mismatch Uncertainty

8003 Technical Specications

Reecon Measurements: When measuring devices with high return loss (>10 dB), reecon accuracy is typically dominated by the eecve system direcvity (Fig. 2), instrument linearity errors, and noise uncertainty. With low return loss devices (<10 dB), reecon accuracy is typically dominated by source match (Fig. 3). Calibraon with an open and short eecvely removes uncertaines due to frequency response of the source, sensors, and signal spling device.

Reecon Accuracy = Instrument Accuracy + Reecon Bridge Accuracy
