INTRODUCTION
1.1.
DESCRIPTION
The Guildline Precision Voltage Divider, with extremely low thermal offsets and built-in
temperature controlled chamber, is ideal for voltage ratio measurements to sub-ppm
accuracy. Input voltages in the range of 10 mV to 1100 V can be divided by ratios of
1:1000, 1:100, 1:10, 1:1, 10:1, and 100:1 with accuracies of 0.5, 0.2, 0.1, 0.05, 0.1, and
0.2 µV/V respectively.
Special care has been taken to minimize thermal offsets and noise. The switches used are
high isolation, low thermal relays. The 7520 can be operated from the front panel touch
screen or by SCPI commands sent over the USB or IEEE Interfaces.
