Now I am creating a new NMR/NQR spectrometer. Soft I write on the NI LabView. I try to abandon the traditional modulator and acquire a DAC capable of producing ready-made RF-pulses.
The only DAC than i finded are SpinCore. But the model PulseBlasterDDS-IV-1000, which would suit me "unable to resume manufacturing". PulseBlasterDDS-300 does not fit the frequency parameters.
Can you recommend alternatives to these devices?
Minimal Technical requirements:
Frequency Range: 5-200 MHz, Ideally, I would like to 5-400 MHz
Number of RF-output: 1 or more
Frequency standart: OCXO or 10 MHz input (Sin)
Frequency Resolution: 1 Hz
Phase Resolution: 1 deg
Amplitude Resolution: 10 bit
Max. RF Amplitude: 1 V
Number of TTL-output: 2 or more
Logical 1 output voltage : 3,3 V
Logical 0 output voltage: 0 V
Max. Instruction time length: 1 day
LabView compatible.
You did not specify the resolution.
There are lots of DACs on the market. Have eg a look on digikey.com, you can find quite some
that meet this for a reasonable price.

Thank you for your comment. Added technical requirements.
Thanks, I looked in this store.
Interesting experience of using the DAC in the experiment, stability, ease of programming, etc.
