Problem with my Lock In Amplifier (SR830)

[OrangeBox]

Hello! 
I'm just starting to work with the device. I have a few questions.
Can I make a triangular reference signal?
Can I transmit the reference signal via GPIB?
sry for my english

This is really a question for SR, but AFAIK the SR830 will only output a sine wave.  If you want to combine your signal with a sawtooth waveform you need to supply it yourself, perhaps using the Aux In but it depends on the amplitude and frequency you require. 

You can set all the parameters of the sine wave via SCPI commands sent over RS232 or GPIB.  There's a LabVIEW driver for the SR830 here - http://sine.ni.com/apps/utf8/niid_web_display.model_page?p_model_id=1536

Thanks for the answer.
I installed the drivers and can change the parameters of the sine wave. But can I change the shape of the reference signal?

Thanks for the answer.)

I installed the drivers and can control the parameters (frequency, phase ...).
Can I change the shape of the reference signal?
I read in the manual that I can send a signal to the TTL input, but there will still be a sine wave. I need a sawtooth waveform

I don't see a saw tooth signal as an option listed in the SR830 manual. Is this something you have implemented before?

[OrangeBox]

Nope.

I understood that I hadn't known a principle of a operation of the lock-in.

I have no more questions))

Thank you!
