1255B y 1252A  Analizador de Respuesta de Frecuencia  10µHz a 1MHz y 10µHz a 300kHz

1255B - Analizador de frecuencia 10µHz a 1MHz con panel frontal ciego

1252A - Analizador de Frecuencia intermedia 10µHz a 300KHz con panel frontal ciego

The 1255 FRA is ideally suited to a wide variety of applications in the fields of electronics and the analysis of electrochemical / biological phenomena.

These include:

• Evaluation of dielectric and semiconductor materials
• Group delay measurements on transmission lines and television circuits
• Pulse transformer and delay line circuits
• Evaluation of wideband amplifiers and switched mode power supplies
• Performance of filters:- insertion loss, bandwidth and ripple
• Corrosion and inhibitor studies
• Organic / inorganic coating analysis
• Development of fuel cell materials
• Studies on animal and plant tissue properties

Impedance measurement can provide greater sensitivity and also more information about the processes than conventional dc methods, particularly when impedance's are high or when low conductivity media are being used. High frequency measurements enable the calculation of solution resistance values, thus enabling corrosion resistant materials and polymer coatings (interfacial capacitance's) to be studied.
Frequency resolution can be optimized with logarithmic sweeps, or spot measurements to minimize analysis time. Data can be plotted during the measurement scan, in standard formats such as Bode plots and Complex plane diagrams.

• The 1255 FRA is a high precision instrument for measuring gain, phase and group delay
• Ideal - when combined with the 1287 ECI - for EIS investigations
• Frequency range 10microHz to 1MHz; 0.2%, 0.2° accuracy
• 130dB dynamic range for accurate filter testing with automatic rejection of noise and harmonics
• Automatic sweeps of frequency, amplitude and bias

IEEE-488 and RS-423 interfaces for automated systems integration.
