Testing Performance of the Delay Amplifier

6.1.1

Introduction

The following fxircgraphs are intended as an aid in the installation and

checkout of the 427. These instructions present information on front

panel controls and waveforms at test points and output connectors.

6.1.2 Test Equipment

The following, or equivalent, test equipment is needed:

(1) ORTEC 419 Pulse Generator

(2) Tektronix Model 580 Series Oscilloscope

(3) 100-ohm BNC Terminators

(4) Vacuum Tube Voltmeter

(5) ORTEC 410 Linear Amplifier

(6) Schematic and Block Diagram for 427 Delay Amplifier.

6.1.3 Preliminary Procedures

(1) Visual ly check the module for possible damage due to shipment.

(2) Connect oc power to the Nuclear Standard Bin, ORTEC 401A/402A.

(3) Plug the module into the Bin and check for proper mechanical

alignment.

(4) Swi tch on the ac power and check the dc power supply voltages

at the test point on the 402A Power Supply control panel.

6.1.4 Delay Amplifier

There are no internal adjustments to be made on the 427; therefore,

testing is simply a matter of observation of the input and output wave

forms.

(1) Connect the output of the 419 Pulse Generator into the input of

the 410 Amplifier.

(2) Set the 410 controls as follows:

INPUT ATTENUATOR

NEG

INPUT POLARITY

2nd DIFFERENTIATION

(inner concentric control)

COARSE GAIN

1 .5

FINE GAIN

INTEGRATION

1st DIFFERENTIATION

(outer concentric control)
