Page 15: Operating The Probe Using The Accessories
Using the accessories Using the accessories The 1153A Differential Probe and accessories 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 applies to the adapters. The figure below shows, in a general way, the use of accessories. - Page 16 To prevent pickup of stray fields when you use extension leads, either the ones supplied with the 1153A or others, dress them carefully as follows: • Connect the leads at right angles to the circuitry under test.
- Page 17 Operating the Probe Using the accessories N O T E Each lead has an input capacitance of approximately 15 pF. This capacitance may limit the bandwidth of your measurement (depending on the impedance of the circuit). Also, CMRR may be affected because of slight differences between the input capacitance of the two leads.
- Page 18 Operating the Probe Using the accessories Adapter The figure below shows the allowed adapter and probe combinations. There are two combination 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 22: Differential Amplifiers And Cmrr
The CMRR of the 1153A Differential Probe is specified at the input of the probe and cannot be affected except 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 measurement, especially at high frequencies. -

Page 26: Probe Troubleshooting
Service Probe troubleshooting Probe troubleshooting Use the following procedures to assist in troubleshooting problems with the 1153A Differential Probe. Preparing the probe for troubleshooting The probe bottom cover must be removed before troubleshooting to allow access to signals where the probe cable connects to the pc board. - Page 27 Service Probe troubleshooting Repeat steps 3 and 4 with the probe connected to the test board in the position shown in the figure below (signal to - input). If the probe output cable is unterminated, or the coax is open, the output signal will be about twice the amplitude of the input signal.

Page 28: Removing And Replacing The Assemblies
Service Removing and replacing the assemblies Removing and replacing the assemblies This section contains procedures for the removal and replacement of major assemblies. C A U T I O N Never remove or install any assembly with the instrument power ON. Component damage can occur. - Page 29 Service Removing and replacing the assemblies Reassemble Probe Reassembly is essentially the reverse of the diassembly procedure. If replacing the PC board, remove the input connectors from the old board and put them on the new one. If replacing the cable, note the orientation of the probe clamp ring on the old cable, remove the ring and put it on the new cable.

Service Removing and replacing the assemblies Replace the bottom cover. Position the cable strain relief and with one hand, hold the cable and top cover together. The flange on the strain relief has a notch that fits over a protrusion in the top cover. C A U T I O N Note where the two pins at the rear of the top cover enter the holes in the PC assembly. - Page 31 Service Removing and replacing the assemblies Reassemble Adapter Reassembling the adapter is slightly harder because you have to align the connector pins and thumbwheel screw, while sliding the inner housing and outer housing together. Be sure the input connectors and output pins are present and seated on the substrate or PC board.
