Notes

Spatial chirp is accurately and easily revealed by tilt in the otherwise symmetrical measured trace.
Pulse-front tilt is accurately and easily revealed by a displacement of the trace along the delay axis.
Absolute wavelength is determined to a few nanometers by the accurately calibrated crystal angle dial.
GRENOUILLE is a second-harmonic generation (SHG) FROG, and hence has an ambiguity in the direction of time, but this one-bit ambiguity can be removed using any of several simple methods.

Feedback on measurement quality is obtained from the retrieved trace (as well as additional optional marginal measurements). Only FROG offers these assurances that a measurement is absolutely correct.
The input-beam mode quality should be good, and the spatial profile measurement helps you to ensure this.
Single-shot measurement is available without modifying the device.
Finally, GRENOUILLE is so easy to use that even aligning your beam into it involves an amazingly simple (~10 minute) procedure.
