X-Y mode on the 453 and 454 requires that you select 'Ch1 only' on the trigger switch that is concentric with the vertical mode switch (Ch1 - Ch2 - Alt -Chop - Add). If the timebases have been

That reminds me that I must resurrect mine. I was frustrated last time it had an outing (quite a number of years back) when it would make contact on one side or the other. Now that may be a little

2 us/div is right in the middle of the fastest set of sweep ranges so I wonder if the sweep control knob has become mechanically decoupled from the actual switch. I am not familiar with how the 453

There are C and C++ compilers for PIC but I always used assembly. The older PIC instruction set architecture is not conducive to good compiler performance but improvements in the later ones make

I think we discussed this here before. The LED version of the 7A13 was released in 1976 which is also when the 7A85 was released so Tektronix had their integrated DVM with readout solution

With one exception that I know of which I would not care to use, practically all microcontroller ADCs lack the resolution and accuracy of the 4000 count integrating ADC Tektronix implemented. However

Oops, I missed that and got it backwards. On mainframes with high power slots, the aluminum shield lacks the punch-out directly adjacent to the top of the interface connector on the high power slot

What do you mean by marked? The slots may be keyed by the user. The aluminum cover over the interface printed circuit board has a circular punch-out above the lower plastic guide rail to indicate to

Hi David With a 100 kHz square wave I see that the sweep is very close to 2 µs/div. Trace looks good with a bit of overshoot, I'll post a picture later if that helps. I set Horiz Display to

As I recall from messing with the CCD calibration, repet mode calibration is finicky. Things I would consider in order: 1. Bad interface connection between the CCD and clock hybrids and the printed

Switch, I think. plunger switch on the plugin unit. On the back panel, there's a hole for the low power slots, and no hole for the high power ones. Harvey > > >

Hi Gang: I am seeking a power transformer, part number 120-095 (old numbering system) or 120-0095-XX (new numbering system).  It is used in the 575 curve tracer.  If you have one to sell please

Does anyone know how the TM500 cabinets are marked for having a high-power bay on the right side?

Hi David, Avalanche pulsers can be designed to accommodate a simple charge line consisting of a piece of coax on the avalanching junction. This is a simple improvement to make. The delay line

Hi, I am looking to find out more information on how the normalisation process is executed and what exactly is performed in each step of the normalisation process in the Tek Spectrum Analyzers

Sorry, Chuck, I meant A/D, not D/A. Ed, for the smoothest user experience you'd want to scan the display consistently, using a timer-driven ISR. The ISR has five states. The first four states light

I tried with different frequencies. Till 10 KHz, I don't see any angle. From 10 KHz, the angle or gap starts to become visible, but is roughly a few degrees, probably less then 3 degrees till 50

Hi Dan, I think I would use the 16 bit programmable timer, and the programmable prescaler to create the 60Hzish signal you need for the motor. It would be a set once, and let it play. If you felt

Hi Chuck,   What compiler do you use to program the PICs?  Is it free or low cost?  Have you programmed anything that involves real time?   I have a power inverter for my telescope that I built

Thanks again for all your help. I'm assuming that a standard aluminum electrolytic low ripple would be a reasonable replacement for C914. The original supplier was Mullard-Philips but I could not
