Safety

To avoid personal injury and to prevent fire or damage to the SA1000X, review and

comply with the following information.

Caution The protection provided by the model can be impaired if it is

used in a manner not described in the user documentation.

SA1000X Safety, Environmental, and Regulatory Information

Attention La protection apportée par le modèle risque d'être

endommagée s'il est utilisé d'une autre façon que celle décrite dans la

documentation utilisateur.

Caution The accessories supplied with the probe have been safety tested.

Do not use any accessories other than those provided.

Attention Les accessoires fournis avec la sonde ont subi des tests de

sécurité. N'utilisez aucun autre accessoire que ceux fournis.

Caution Connect the probe ground lead to earth ground; use ground lead

only for connections to earth ground. Always make sure the probe and the

measurement instrument are grounded properly.

Attention Reliez le fil de terre de la sonde à la terre; n'utilisez le fil de

terre que pour les connexions à la terre. Assurez-vous toujours que la

sonde et l'instrument de mesure sont correctement mis à la terre.

Caution Connect the probe output to the measurement instrument and

connect the ground lead to earth ground before connecting the probe to

the circuit under test. Disconnect the probe input and the probe ground

lead from the circuit under test before disconnecting the probe from the

measurement instrument.

Attention Connectez la sortie de la sonde à l'instrument de mesure et

connectez le fil de terre à la terre avant de connecter la sonde au circuit

à tester. Déconnectez l'entrée de la sonde et le fil de terre de la sonde du

circuit à tester avant de déconnecter la sonde de l'instrument de mesure.

Caution Do not exceed the maximum ratings of the probe. Comply with

the voltage versus frequency derating curve in Figure 1.

SA1000X Safety, Environmental, and Regulatory Information

Attention Ne dépassez pas les valeurs de spécifications maximales de la

sonde. Respectez la courbe de réduction de charge représentant la tension

en fonction de la fréquence de la Figure 1.

Caution Avoid open circuitry. Do not touch connections or components

when power is present.

Attention Évitez les circuits ouverts. Ne touchez pas les connexions ou

les composants lorsque le matériel est sous tension.

Caution Do not operate the probe with suspected failures.

Attention N'utilisez pas la sonde en cas de suspicion de défaillances.

Using the Probe

Operating Basics

The SA1000X is system-independent; its standard BNC connector can be plugged

into any measuring instrument with a 50 Ω input. The SA1000X is suitable for

measurements in all frequency ranges.

The T-shaped housing allows many probes to be positioned next to each other in a

chain, which allows for many simultaneous measurements. Adjacent SA1000X active

probes can contact square pins to 2.54 mm pitch.

When using the SA1000X, ensure that the input coupling of the measuring

instrument is set to 50 Ω and that the SA1000X is connected to the power supply.

The SA1000X is protected against electrostatic discharge voltage (ESD).

Notice

SA1000X Safety, Environmental, and Regulatory Information

To ensure accurate performance and protection, avoid mechanical shock

to the probe. Do not bend or pull the probe cable.

Due to the nature of open probes, there may be susceptibility to outside

interference.

When to Calibrate the SA1000X

The first time the SA1000X requires user calibration depends on how much time has

elapsed between its factory calibration and the first time you use the probe.

Complete the following steps to determine when you need to perform your first

calibration of the SA1000X.

1. Refer to Date Calibrated on the calibration certificate included in your kit.

This is the date of the probe's factory calibration.

2. Compare the date you are first using the probe to the date of the factory

calibration, and perform your initial calibration as follows:

First-Time Use of Probe When to Calibrate

<1 year aer factory calibration No more than one year aer first-time use

≥1 year, <2 years aer factory calibration No more than two years aer factory calibration

≥2 years aer factory calibration Before first-time use

Once you have determined the next calibration date, mark the date on the sticker

supplied with the probe and apply the sticker to the side of the probe. Perform

subsequent calibrations of the SA1000X at one-year intervals.

Maintenance

To clean the exterior of the probe, use a so cloth moistened with either distilled

water or isopropyl alcohol. Allow the probe to dry completely before use.

Specifications

Definitions and Conditions

Specifications are typical and are published as general information to the user.

Specifications are valid under the following conditions unless otherwise noted.

■ SA1000X warmed up for at least 30 minutes

■Environmental conditions within the probe's specified limits

Electrical Specifications

Attenuation ratio 10:1, ±0.5% (DC)

Dynamic measuring range ±8 V

Bandwidth (probe only) 1.0 GHz

Maximum rated input voltage 20 V

Notice Applying input voltages outside the specified limits can destroy

the probe's amplifier.

■To counter harmonic distortion and avoid input linearity errors, the

maximum amplitude of the input signal should not exceed the dynamic

measuring range limits stated by Figure 1.
