1743A - Agilent HP Analog Oscilloscopes

The Agilent HP 1743A 100MHz Delta Time Interval Oscilloscope is a dual-channel, powerful oscilloscope with a great Delta-time capability.
Delta time is a function that you use to place markers at selected places then the scope measures the difference in time.
It can do this since it has a 100MHz counter BUILT-IN.
The accuracy is really good because it is crystal-controlled.
Read the time difference on a bright red LED display that does not interfere with the view of your signal.
Now, here is the powerful part.
It measures the time difference on channel A alone, B alone, or between A AND B, or even between either channel and the trigger view.
Obviously, it has trigger view.
It has selectable input impedance.
This is so that you can choose 50 ½ to match the output impedance of an accurate standard.
You could also choose 1 M½ to avoid interfering with the operation of the circuitry that you''''re testing.
The CRT is a large 9.5 x 12 cm.

• Sweep ranges from 50 nS to 2 S
• Sensitivity of 5 mV to 20 V/div with a basic accuracy of ±2%
• Display modes are Main timebase, Æ-Time, Main Intensified, Mixed, Delayed timebase, and Mag X10
• Channels can be displayed as A, B, A versus B (horizontal), ALT, CHOP, ADD, Trigger View (vertical), and Third-Channel Trigger View
