Getting Started
Using AC Power
Use only the AC adaptor provided with the generator to avoid operator injury and damage to the
generator.
Using Battery Power
The generator uses six AA rechargeable nickel metal hydride (NiMH) batteries, which can be re-
charged about 1000 times.
You may use alkaline batteries instead, but not while the AC charger is connected to the generator.
Only NiMH batteries can be safely recharged in the generator.
All batteries in the generator must be the same type.
The supplied batteries may not come fully charged. Use the supplied AC charger to charge the
batteries for at least 18 hours. The AC adaptor may be used to operate the generator and to recharge
the batteries at the same time.
With fully charged batteries, the generator should operate for about 8 hours using VESA mode. Using
the LCD backlight, DVI, NTSC/PAL, or RF features will reduce the battery life. The generator displays a
low battery message when the NiMH batteries need recharging, or when the alkaline batteries need
to be replaced.

Reloading Standard Formats
If you modify or delete standard formats, you can restore the original formats by reloading the
standard formats.
To reload the standard formats:
1. Select Options > Clr_Fmts to delete all formats, including user-created formats.
2. Select Options > Reload Fmts to restore the standard formats to their original memory locations.
The standard formats will replace any user-created formats in the original memory locations.
User-created formats in locations not previously occupied by a standard formats will not be
replaced.

Setting Power Save Preference
When the Power Save preference is on, and the generator is on battery power, the generator will turn
off after 30 minutes of no front panel activity.
If the generator is running a test sequence in Burn-in mode, the Power Save preference is ignored.
To set the Power Save preference, select Options > Pwr Save.

Calibrating
Model 700 and 701 generators use programmable hardware to set the amplitude calibration factors
for analog video outputs. These calibration factors are stored in Flash EPROM, and are not lost if the
batteries are run down or removed.
Quantum Data calibrates the analog video and sync output amplitudes in new generators to pub-
lished specifications. You can recalibrate these amplitudes over a nominal range to meet your
specific testing conditions.
WARNING: Recalling the original factory calibration settings is not possible after saving
your own settings.
Equipment Needed for Calibration
•DC voltmeter capable of measuring from 0 to 1 volt with a minimum resolution of 2 millivolts
•Precision 75 ohm (+/- 1%) input terminator for the voltmeter
•Test cable to connect the voltmeter to the R, G, B and ground pins on the VGA connector
•Oscilloscope with a precision 75 ohm (+/- 1%) input impedance and suitable gain and band-
width to display a 1.00 Volt pk-pk signal with 3.579 MHz color carrier
•75 ohm coaxial cable to connect the oscilloscope to the BNC TV output
•Vector scope

Calibrating
Calibrating Outputs
1. Select Options > Calibrate > Reset to set the generator’s
calibration factors to default nominal values.
2. Press Options > Calibrate > Full Scale.
3. Set the voltmeter’s scale factor to be able to measure a nominal
1000 millivolts DC.
4. Using a VGA-to-BNC cable, connect the generator’s red output to
the positive input on the voltmeter, with a 75 ohm (+/- 1%) input
terminator. Connect the negative lead of the meter to any ground
pin.
5. Select R_FS+ or -R_FS to set the DC output level to 1000 mV
+/- 3 mV.
6. Repeat steps 4 and 5 for the green and blue outputs.
7. Select Save.
8. Select Options > Calibrate > Zero.
9. Connect the red output to the positive input of the voltmeter.
10. Select R_Zero+ or -R_Zero to set the DC output level to 0 mV +/- 3 mV.
11. Repeat steps 9 and 10 for the green and blue components.
12. Select Save.
13. Select Options > NTSC_CAL.
14. Adjust the oscilloscope's timebase and sweep trigger to view the entire waveform. Adjust the
G_NTSC so that its chrominance is 100 IRE or 714mV.
15. Using a vector scope, use the R_NTSC and B_NTSC options to adjust the red and green outputs
using so that their signals align with the 2% boxes.
16. Press Save.
Note: The modulated RF output does not have any calibration settings.
