SPECIFICATION
INTRODUCTION
The PG 500 Pulae Ganantor is afast-rtaatlma pulsa aoifca
producing narrow ractangUar pulses at arapamion rata of 50
KHz.The PQ 509 can deliver acontinuous pulse train at an
anplituds of 25 votts noan output load of 50 ohms.
The PG 509 Pulae Ganarator Is aTM 500 Series piug-ln

Insertion In aTM 500 or TM 5000 Sarias Power liAoduia
htainframa for nartscing to basic power suppliea.
The PG 509 Pulse Garwator was primarily dasignad to be an
negrai part of ataat systam. Flgua 1-1 rtiows primary
components and cormactions immedlataly related to the Pulse
Generator metypical system. Other than the System Coraroller.
Device Under Test, and PG 509, thaea are:
•Aprogranwnabla attenuator {TEKTRONIX AT 5010, or
equivalent); used to provtda system salaction tor the
daTse of attenuation required.
•Ahigh frequency multiplaxar/switcher
(TEKTRONIX SI 5010, or equivalent); used to route inputs
and outputs between Inatrumeres and taat devloas while
irder system control.
Note that wNia the PG 509 Is not uider diract (^Bcorarol, It Is
typically directed by instruments that are.m amostly Tektronix
insitumerB configLration, this would typically mean that the
PQ509 be installed In aTM 5000 (programmable piug-ln
