Can this sweep frequencies, or is it limited to discrete set frequencies, i.e. 280, 320, etc.

If you blow up the picture you will see the center dial. All set frequencies are visible

Limited to set frequencies. You move the dial to what you want...but sweep is not available. They are preset.

It only does set frequencies -- 20-, 28-, 32-, 42-Hz ... up to 150 KHz. Note that there is a fair amount of variation between selected frequency (e.g. 100 Hz) and actual output (e.g. 101.4 Hz), so I would not use it to calibrate frequency devices without a secondary measurement instrument (DVM,Tach, etc.) to verifiy frequency. It is a great little portable inexpensive battery-powered signal source -- TSA allows it to be carried on a plane too. We have a purchased around a dozen over the years. You can adjust amplitude of Sin/Sqr waveform with pot in upper right and the -20db toggle can be handy as well. It only does set frequencies -- 20-, 28-, 32-, 42-Hz ... up to 150 KHz.

Yes, as long as it is has the same frequency. Look up in your operator manual.

I do not know for sure, but they all operate on the same frequencies. Most likely you can. Ours work great.

Even some frequency setup for different animals, from my experience, it works very weakly

Sorry i have not tried it yet. But i guess it will not work on data because of frequency differential.

The sampling rate should be at least twice the data rate according to Shannon's Law. I haven't checked it on high frequency devices over 5 MHz. or so. The proof of the picking would to be if it would display the output from a signal generator or a random antenna connected to it and transmitting nearby within the 20 or 30 meter bands. I don't recall saying it had a 72 MHz. bandwidth, if it did, everybody would have one and they wouldn't be as cheaply priced. Check out the print on the website and there might be a detail or two: Sain DSO (oh--not zero,)203. I haven't used mine in a while, I just like gadgets, fool around with them for a while until I get bored or figure out a better way to do the same thing. Good luck...

My husband has a paper with frequency codes he would use. Or look in your manual for codes. Each state has different codes. Try police scanner codes.com for your area.

Don't know. Never thought of it. However tuning on to a station is not "clean". Sometimes you have to go beyond then go back to get a precise tuning.

At the present I'm using only 3-5 channels while scanning ,each of those has approx. 8-12 sub groups which I've programmed so I'm tuned into and scanning 60freqs. On average . I've got other groups programmed into channels wich are 50-55 freqs per channels. With 20 channels total. If you buy this please read the manual and go to radio reference for freqs.. I'm tuned into police /fire, sheriffs /jails , tactical/swat, DOT, state patrol., municipal workers, etc....

No. That is an entirely separate frequency. Check out cell boosters from Wilson electronics. They make what you would need.

Hello, it can do up to 99 intervals in one set. You have up to 10 sets. Thanks for your interest

It is fine to have them all in the same frequency band. I have 4 running in the same band with no issues.

You probably can do what you are asking as long as the two units are receiving the same frequency. The one I bought has a number (sticker) on the PA unit itself and a matching number on the hand held mic. This indicates to me that there are several different frequencies with these units. You would need to request matching units.

I would not think the two systems interchange. My guess is different frequencies. Check with the manufacturer.

No in fact I would recommend that you have really good eq first. All this does is captures crazy frequencies and blocks them. If you have bad eq,bthen it will begin to grab good frequencies too... and I had to reposition it after the eq

i believe you can make it do that. but you have to have it tuned to a certain frequency. But i'll tell you its just fine with out it. Love this item.

You can scan various frequencies. I don't have the frequency of your police channels, so I can't answer your question.
