Vo ltage Probe Check Wizard

You can use the Probe Check Wizard to verify that a voltage probe is operating properly. The wizard does not support current prob es.

The wizard helps you adjust the compensation for voltage probes (usually with a screw on the probe body or probe connector) and set the factor for the Attenuation option for each channel, such as in the CH 1 MENU ► Probe ► Vo l ta g e ► Attenuation option.

TDS1000B/2000B Series Oscilloscope User Manual 5

Getting Started

You should use the Probe Check Wizard each time you connect a voltage probe to an input channel.

To use the Probe Check Wizard, push the PROBE CHECK button . If the voltage probe is connected properly, compensated properly, and the Attenuation option in the oscilloscope VERTICAL menu is set to match the probe, the oscilloscope displays a PASSED message at the bottom of the screen. Otherwise, the oscilloscope displays directions on the screen to guide you in correcting these problems.

NOTE. The Probe Check Wizard is useful for 1X, 10X, 20X, 50X, and 100X

probes. It is not useful for 500X or 1000 X probes, or for probes connected to the EXT TRIG BNC.

NOTE. When the process is complete, the Probe C heck Wizard restores the

oscilloscope se ttings (other than the Probe option) to what they were before you pushed the PROBE CHECK button.

To compensate a probe that you plan to use with the EXT TRIG input, follow these steps:

1. Connect the probe to any input channel BNC, such as to CH 1.

2. Push the PROBE CHECK button and follow the directions on

the screen.

3. After you verify that the probe functions and is compensated properly, connect the probe to the EXT TRIG BNC.

Probe Attenuation Setting

Probes are available with various attenuation factors which affect the vertical scale of the signal. The Probe Check Wizard veriﬁes that the attenuation factor in the oscilloscope matches the probe.

As an alternative method to Probe Check, you can m anually select the factor that matches the attenuation of your probe. For example, to match a probe set to 10X connected to CH 1, push the CH 1 MENU ► Probe ► Vo l t ag e ► Attenuation option, and select 10X.

NOTE. The default setting for the Attenuation option is 10X.

If you change the Attenu ati need to change the oscilloscop e Attenuation option to match. Switch settings are 1X and 10X.

NOTE. When the Attenuation switch is set to 1X, the P2220 probe limits the

bandwidth of the oscilloscope to 6 MHz. To use the full bandwidth of the oscilloscope, be sure to set th e switch to 10X.

Current Probe Scaling

Current probes provide a voltage signal proportional to the current. You need to set the oscilloscope to match the scale of your current probe. The default scale is 10 A/V.

For example, to set the scale for a current probe connected to CH 1, push the CH 1 MENU ► Probe ► Current ► Scale option, and select an appropriate value.

Self Calibration

The self calibration r outine lets you op timize the oscilloscope signal path for maximum measurement accuracy. You can run the routine at any time but you should always run the routine if the ambient temperature changes by 5 ° C (9 °F) or more. The routine takes about two minutes.

For accurate calibration, power on the oscilloscope and wait twenty minutes to ensure it is warmed u p.

To compensate the signal path, disconnect any probes or cables from the input connectors. Then, access the UTILITY ► Do Self Cal option, and follow the directions on the screen.
