+# Rigol scope stats in Go
+
+This tool allows you to pull measurement statistics from a Rigol Oscilloscope over the network connection and outputs them in CSV format. I've tested it with my DS1054Z so far.
+
+It can also take screenshots at the same intervals. 
+
+## Usage
+
+    # go run .\rigol.go -host 192.168.7.90 -channels 2 -clear -interval 60 -vmax -vmin -screen > file.csv
+
+Options are as follows. If you have more than 5 statistics displayed (on my scope at least) then reading them takes a few seconds as it has to recalculate the values as the others scroll off the list.
+
+    -channels int
+            number of channels to collect (default 4)
+    -clear
+            clear stats after collection
+    -count int
+            number of measurements to take. -1 = no limit (default -1)
+    -freq
+            include frequency
+    -host string
+            hostname or IP address (default "rigol")
+    -interval int
+            number of seconds between readings (default 1)
+    -port int
+            tcp port to use (default 5555)
+    -screen
+            collect screenshots in PNG format
+    -vavg
+            include Vavg (default true)
+    -vmax
+            include Vmax
+    -vmin
+            include Vmin
+    -vpp
+            include Vpp
+    -vrms
+            include Vrms
+
+## Setup 
+
+You can configure the scope over the network too - this is especially useful if you want to set specific options across a number of tests. 
+
+I use the following example quite frequently - telnet to the scope on port 5555 and send the following commands. It's worth doing a few at a time or sometimes one will get missed if you paste in too many lines at once. 
+
+    *RST
+
+    :TIM:MODE ROLL
+    :TIM:MAIN:SCAL 5
+    :ACQ:TYPE HRES
+    :DISP:TYPE DOTS
+
+    :CHAN1:BWL ON
+    :CHAN1:UNIT AMP
+    :CHAN1:COUP DC
+    :CHAN1:PROB 100
+    :CHAN1:RANG 4
+    :CHAN1:OFFS -1.5
+    :CHAN1:DISP ON
+
+    :CHAN2:BWL ON
+    :CHAN2:UNIT VOLT
+    :CHAN2:COUP DC
+    :CHAN2:PROB 1
+    :CHAN2:RANG 8
+    :CHAN2:OFFS -3
+    :CHAN2:DISP ON
+
+    :MEAS:STAT:ITEM VAVG,CHAN1
+    :MEAS:STAT:ITEM VAVG,CHAN2
+
+    :CURS:MODE TRAC
+    :CURS:TRAC:SOURce1 CHAN1
+    :CURS:TRAC:SOURce2 CHAN2
+    :CURSor:TRACk:AX 586
+    :CURSor:TRACk:BX 586
+
+Detail for these can be found in the Rigol Oscilloscope Programming guides, but in summary this sets the scope to a rolling 60s view, reading a range of -0.5 to 3.5A on Channel 1 and -1 to 7 V on channel 2, and enables the cursor for realtime measurements.
