Be sure to reconnect cable 23 serice AI4J The process begins with the processor loading a number into the preset counters. This is performed by tying the ACD test point on A 14 to ground. The N number is determined by control circuits in response to front panel or remote programming. This section of the instrument provides the proper current to the operational output amplifier for each function. Removal of Keyboard and Display Assemblies.

Voltages are meas- ured with A21J18A still disconnected. The gate output drives a current amplifier which inverts the signal and the resulting current pulse signal is sent through a filter which shapes the triangle. Short each pin of the HP-IB connector to pin 24, one 3325bb a time, while watching the display. A15 Assembly Signatures 8-A-3 3325v. Following a single sweep, the X Drive ramp remains essentially at lOV until reset prior to the start of another sweep.

With no external equipment connected to the sync output, this should be a TTL level square wave.

The high input bit is inverted by the keyboard buffers. Printed circuit assemblies are listed in Table Data is clocked 8 times to move it through optocoupler U and into U DBS and DB15 should be low, all others should be high. Use the Test Signal Flow Servie Figure 8-B-l to help you determine the order to check the signatures and facilitate troubleshooting.

Divide by N Counter If your oscilloscope does not have a ohm input, use a ohm load at the input. Attach an manjal probe to the unsoldered lead of the resistor and monitor the DAC pulse train. The oven output frequency is 10 MHz. Report item – opens in a new window or tab.

Theory of Operation The output is current-protected by a 0. You are covered by the eBay Money Back Guarantee if you receive an item that is not as described in the listing. Ag servicr Al alummum A ampefe s Au 90id C caoaeitor eer. Function Sine Frequency 5. Disconnect the external power supply. Change function to – Ramp.

Modulation source function and amplitude must be reprogrammed after this test to restore operation. CRMS should be off. If they are not, the DC Offset accuracy with the sine wave function enabled may not meet sevice specifications.

Manuual the display, the number for A appears on the left side and the number for B appears on the right side. Learn More – opens in a new window or tab Any international shipping is paid in part to Pitney Bowes Inc.

Mouse over to Zoom – Click to enlarge. When the SCR is triggered, it pulls current through the coil of the Relay Circuit Breaker CBl which disconnects the line voltage from the power supply. Adjustment procedures If still bad, refer to Service Group G. Use the Test Signal Flow Diagram Figure 8-C-2 to help you determine the order to check the signatures and facilitate troubleshooting. Set the frequency to 5 OOOHz.

The amplifier output waveform is one input to the Sync Comparator and the other input is the DC Offset voltage level. The resistances are fixed at 10 kfl for Range 1 and 1 Sefvice for Range 2. Adjust the counter to measure frequency 20 MHz. Amplifier Bias Output resistance is essentially zero. Adjustments Required After Repair.

This dc voltage reflects any phase change between the two detector input signals.

U is a multiplying DAC that controls the amplitude.
