Agilent / HP / Keysight 8753C

The Agilent/HP 8753C Network Analyzer is a vector network analyzer which can measure both amplitude and phase properties associated with the reflection and transmission of RF electrical signals.

The 8753C is one of the most widely used network analyzers which offers high accuracy in measuring S-Parameters, reflection and transmission parameters.

The Agilent 8753C also displays the Smith chart, plot measured data on it, and provides adjustable markers that show the calculated impedance at the marked point in a several marker formats.

The test sequence function of the 8753C allows rapid and consistent execution of complex repetitive tests with a single keystroke. In sequencing mode, you make the measurement once form the front panel, and the instrument stores the keystrokes so that no additional programming expertise is required.

You can even set other HP-IB instruments with a test sequence. Other productivity enhancements include a plot/print buffer, limit testing, arbitrary frequency testing, and marker tracking functions.

Segmented calibration and interpolative error correction allow you to apply vector accuracy enhancement over a subset of the frequency range that you initially calibrated the HP 8753C.

The integrated synthesized source provides > 100mW of output power, 1 Hz frequency resolution, and linear, log, list, power, and CW sweep bytes. Three tuned, 300 KHz to 3 GHz (Option 006 extends to 6 GHz) receivers allow versatile independent power measurements or simultaneous ratio measurements over a 100 dB dynamic range.

By using the HP 85047A Test Set with the HP 8753C, the reflection and transmission characteristics of the device under test can be investigated from 300 kHz to 3 GHz or from 300 kHz to 6 GHz with the test set’s frequency doubler enabled.

Non-linear device characterization is possible with the HP 8753C. Swept second and third-harmonic levels of an amplifier can be displayed directly or relative to the fundamental carrier (dBc) when employing the optional harmonic measurement capability (Option 002).

Amplifier harmonics up to 40 dBc can be measured quickly and conveniently on a swept- frequency basis for fundamental signals as low as 16 MHz, using the same test configuration provides leveled absolute power to devices that are sensitive to absolute input or output levels.

The HP 8753C automatically controls an HP 436A, 437B, or 438A Power Meter to set the power anywhere in the configuration with power meter accuracy.

The HP 8753C has the capability to perform mixer tracking and conversion loss measurements. These are possible because the tuned receiver can be offset from its synthesized source by the LO frequency of the mixer. Both fixer and swept IF measurements can be made.

Time domain responses can be displayed by the HP 8753C with Option 010. The instrument computes the inverse Fourier transform of the frequency domain data to display the reflection or transmission coefficient versus time.

The HP8753C offers two time domain modes. The low-pass mode provides the traditional Time Domain. The low pass mode of HP 8753C provides the traditional Time Domain Reflectometer (TDR) measurement capability and gives the response of the network to a mathematically simulated step or impulse response.

The bandpass mode time domain mode of HP 8753C has only impulse stimulus and no frequency restrictions. The HP 8753C provides the time domain response of frequency selective devices such as SAW filters.

Gating may be used to selectivity isolate a single response to view the frequency domain response of individual portions of a component without disturbing the circuit itself.
