Hi:
Would anybody care to offer an opinion on this little minimalist signal generator on eBay?
http://www.ebay.com/itm/200673882707?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649Right now, I have a pair of elderly Systron Donner pulse generators that seem best suited to classroom demonstrations of what a crappy, ringing square-ish square wave looks like. :-/
Extremely high bandwidths are not required. Just something producing clean square, sine, and sawtooth waves that I can afford.
Thanks in advance:

PS Specs from the auction below:
Description:
AD9851 uses advanced DDS technology, direct frequency synthesis, can produce spectrally pure, frequency and phase can be, programming control and stability of a good sine wave. Increased relative to the AD9850 internal multiplier 6, the reference clock just 30MHZ, 180MHZ, they would get the system clock. Design output 0 ~ 70MHZ, effectively reducing the external frequency source phase noise generated.
AD9851 Functional Description:
* Using AD9851 DDS chip, the external clock is active 30MHZ crystal.
* Using seventh-order elliptic filter, cutoff frequency 70MHZ, step 0.04HZ; phase 16, step 11.25.
* Sinusoidal output signal, square wave signal, amplitude stability.
* 50% duty cycle square Bomo recognized.
1, the product design frequency range of 0 ~ 50MHz, step 1Hz, frequency output stable.
* Output waveform: sine wave, square wave.
* Output signal amplitude stability: 1Vp-p.
* Output frequency control: Four keys to operate independently, simple and quick.
2, this design can be disassembled into separate modules and AD9851 51 experimental test module
* LCD removed, then the short circuit between the AD9851 AT89S52 and remove the child, the circuit board on the left is the independent board of 51 single-chip experiment (with SPI download port), the circuit board on the right is independent of the AD9851 experiment board.
* Output interface: signal generator dedicated connector, and a complimentary special signal generator output line.
Packing list:
1 * DDS signal generator
1 * BNC Signal Cable
