Arb generator that is worth owning?

(1/5) > >>

FriedMule:
I have read, looked reviews, opinions and much more but to me does it look like everyone either gain to recommend there product or only have good opinions about what they own because thy do not know others. All except on this site where I have fund many different opinions on what is great for the tread starter. Unfortunately is it hard for me to understand or decide if there need is the same as mine. Hope you please will help to point me in the right direction. :-)

I know that Siglent, Rigol, Owon, Agilent and other do make units but I can not fully understand and decide if the specifications are true or inventions, like a Siglen should be better then an Agilent, on the other hand is Agilent often 10 X the price.

Here is what I think I need (or better):

* Cost:Prefered below 500$

* Waveform type max frequency: square, sawtooth, arb, sine 10MHz

* Bits, 14 or 16: High Precision

* Max amplitude and current: 5V ?A

* 2 equal channels: Yes

* Combine channels: Yes

* Phase control: yes

* Output protection: Short

* External clock input: yes 10MHz

* External trigger input: Preferred

* USB pen reader

tautech:
SDG1032X easily meets all your requirements.

However SDG2042X for 16 bit and touch display is right at the top of your budget.

Check the datasheets as I think they both can supply 200mA.

BK Precision 4053B / 4054B line is really nice.  I have a single output 4045B which I use often.  I had an HP33120A, 15 MHz Arb, which was good and can be had used, for under $500.00, though I think the BK is easier to use.

bd139:
I like the Rigol DG1022Z. Cheap, two channels, excellent performance (better than most of the rivals) and you can crack it to 60MHz.

jpb:
I think almost all arbs (there are exceptions of course) have an internal resistance of 50 ohms so that they supply 20V to high-Z and 10V to 50 ohms so they can supply 200 mA at 10V into 50 ohms.
Lowering the impedance will increase this a bit but at a lower voltage.

Imax = 20V/(50 + R).
Vmax = Imax.R = 20R/(50 + R) or (20 - Vmax)*R = 50*Vmax

At 5V out R can be 250/15 = 50/3 ohms and Imax = 300 mA

This is assuming that they can supply up to 400 mA into a short circuit - they may have a minimum load impedance.
