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.

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).

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 aer factory calibration No more than one year aer first-time use
≥1 year, <2 years aer factory calibration No more than two years aer factory calibration
≥2 years aer 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.
