  • Page 11 The following paragraphs cover system preparation and initial adjustments. Power Requirements The 1141A/1142A probe system (specifically the 1142A) requires a power source of either 90 to 132/198 to 264 Vac, 47 to 440 Hz, 25 VA maximum. C A U T I O N Before connecting power to this instrument, be sure the line voltage switch on the rear panel of the instrument is set properly.
  • Page 12 Initial Adjustment For a given combination of 1141A Differential Probe and 1142A Probe Control and Power Module, you may want to adjust the Offset Null and DC Reject Gain. Typically, you need to make these adjustments only once, before the probe is first used. You can make them any time to optimize the system.
  • Page 13 Operating the Probe Recommended Test Equipment • Offset null zeroes the dc level at the output of the probe. The range of adjustment is about ±4 mV. • DC Reject Gain adjusts the gain of the dc reject circuit to accurately null the dc component of an input signal.
  • Page 14 Using the Accessories The 1141A Differential Probe and accessories are designed to provide a variety of ways to connect to circuitry and make measurements. In the descriptions, any method used to connect to the probe signal inputs also applied to the adapters. The figure below shows, in a general way, the use of accessories.
  • Page 15 Operating the Probe Recommended Test Equipment Figure 1-7 Basic Accessory Connections Probe Tips Probe tips fit into the receptacles in the probe and are held in place with probe tip caps. If necessary, you can solder the probe tips into a circuit or wires can be soldered to the tips.
  • Page 16 To prevent pickup of stray fields when you use extension lead, either the ones supplied with the 1141A or others, dress them carefully as follows: • Connect the leads at right angles to the circuitry under test.
  • Page 17 Operating the Probe Recommended Test Equipment Adapters There are three adapters for use with the differential probe. Two adapters are attenuators, a 10x and a100x. The other is an ac adapter for blocking dc from the probe input. The adapters are installed on the probe after the probe tip caps and probe tips have been removed.
  • Page 18 Operating the Probe Recommended Test Equipment Adapter Combinations The figure below shows the allowed adapter and probe connections. There are two specific combinations that should not be used. • Do not attach the ac adapter between an attenuator adapter and the probe. An attenuator adapter must be terminated by the input resistance of the probe.
  • Page 19 Operating the Probe Recommended Test Equipment Connector Compatibility The following are general connector characteristics for the probe, adapters, and accessories. • The female connectors on the probe, adapters, and other accessories are designed to mate with 0.030-inch round or 0.0250-inch square pins. •...

  • Page 21 Operating the Probe Recommended Test Equipment To use dc reject: Remove the ac adapter if it is installed. On the front panel of the 1142A, press Local. Under DC Reject on the front panel, press 5.0 Hz or 0.5 Hz individually, or 5.0 Hz and 0.5 Hz simultaneously to get 0.05 Hz.
  • Page 22 Operating the Probe Recommended Test Equipment To use ac coupling: Attach the ac coupling adapter to the input of the probe or the input of the attenuator adapter. On the 1142A, press Local and Zero offset. Remote operation For automatic test applications, the coupling and offset functions provided by the 1142A Probe Control and Power Module can be remotely controlled through a connector on the rear panel of the module.
  • Page 23 Operating the Probe Recommended Test Equipment Function Select The easiest way to control the function select lines is contact closures between the lines and Digital common (pin 2) of the remote input connector. (TTL compatible control signals can be used; but to avoid problems with ground loops, they must be electrically isolated.) The following truth table shows the functions provided by the function select lines.
  • Page 24 The CMRR of the 1141A Differential Probe is specified at the input of the probe and cannot be affected expect by adjustments in the probe. However, the way the probe is connected into the circuitry being tested can have a big influence in the overall result of the measurement, especially at high frequencies.

  • Page 60: Theory Of Operation

    The following discussion covers block-level theory for the 1141A/1142A differential probe system. Refer to the block diagram below. The differential probe system consists of two units, the 1141A Differential Probe with its accessories and the 1142A Probe Control and Power Module. For purposes of the following discussion, these will be called the probe and the control module respectively.

  • Page 61: Differential Probe

    Service Theory of Operation Differential Probe The probe contains a two-path differential amplifier with unity gain. It is implemented on a double-sided surface-mount PC board with the high-frequency path on one side and the low-frequency path on the other. The two paths are split directly after the differential input connections.

  • Page 62: Attenuator Adapters

    Service Theory of Operation Offset Functions There are two offset functions developed in the control module: variable offset and dc reject. A variable offset voltage with coarse and fine adjustments can be selected by the front panel controls.
