Operating Modes

1. When operating in the output mode the T150

has the capability to drive loads up to 1

kOhm with TTL levels. The standard output

amplitude is a 5 volt ± 10% p-p square wave.

2. When operating in the read (input) mode the

T150 can monitor frequencies with

amplitudes ranging from 1 to 100 volts. The

waveform shape can be square, sine or

triangular.

Accuracy

The T150 is checked against an NIST Traceable

reference before shipment to verify that each

range falls within the 0.01% ±1count of full

scale. Since the accuracy of this particular

product is based on a very stable quartz

crystal, the T150 should stay well within its

operating specification without the need for

calibration for periods of 1 year or more.
