The 2465A, 2455A, and 2445A

The TEKTRONIX 2465A, 2455A, and 2445A portable oscilloscopes have four vertical channels with DC to 350 MHz, 250 MHz, and I 50 MHz bandwidths. Deflection factors run from 2 mV to 5 V per division, in a 1-2-5 sequence, with either 1 M ohms or 50 ohms input resistance, in channels 1 and 2. Either AC or DC Input coupling is available at 1 Mohms. Channels 3 and 4 give 0.1 V or 0.5 V per division, with 1 M ohms input resistance, and DC coupling. With the standard 1 OX probes, channels 1 and 2 display 20 mV to 50 V/division and channels 3 and 4 display 1 V or 5 V/division.

The trigger systems work automatically for most signals. They operate in various modes, from any channei,with couplings for a wide range of signals. The 2445A triggers from DC to 250 MHz. The 2455A and 2465A trigger from DC to 500 MHz.

Sweep speeds range from 1 .5 s to 1 ns per division on the 2445A and 2455A and to 500 Ps per division on the 2465A, including the effects of the Xl 0 magnifier and the calibrated variable between 1 -2-5 steps. Horizontal displays include A-Sweep, B-Sweep (delayed), A alternated with B, and CH 1 (for X/Y displays).

The SETUP features, AUTO, SAVE, and RECALL, save time and prevent errors, whether you are a novice operator or a master. AUTO Setup works with almost any signal. For repeating measurements, the Save and Recall functions record and restore as many as 30 instrument setups, including the extended-function options. Setups can be recalled either immediately or sequentially.

Digital readouts of time, voltage, scale factors, trigger levels, and auxiliary information also save time and reduce errors.

With the available Counter/Timer/Trigger (CTT), Option 06 or Option 09, measurements require even less effort and give better accuracy. The CiT Increases trigger selectivity, especially in digital systems. Option 09 includes the CiT and a 1 7-bit Word Recognizer (WR). The available Television/Video (TV) enhancement, Option 05, can trigger at any desired point in a frame and it can reduce the effects of ac coupling and hum in a video signal. The available Digital Multimeter (DMM) measures dc voltage, dc current, ac rms voltage, ac rms current, resistance, and temperature with floating inputs.

Instruments with CiT include MENU in the Trigger Mode selection. The WA adds a Word Recognizer Probe connector on the rear panel. The TV enhancement adds LINES, FLD1 , and FLD2 Trigger Coupling.

The. available GPIB interface accesses all controls and digital readings. The interface adds GPIB status indicators, Just above the CAT. See the 24X5A/2467 GPIB (Option 10) Instrument Interfacing Guide for information on integrating the instrument into a GPIB system.

The 2465A CT includes CiT and WA (Option 09) and GPIB (Option 1 0). The 2465A DM adds DMM (Option 01) and also includes CTT and WA (Option 09) and GPIB (Option 1 0). The 2465A DV adds TV (Option 05) to the features of the 2465A DM.
