SIGLENT’s new SDS1104X-E Super Phosphor Oscilloscope has a 100 MHz bandwidth and 4 analog channels. It has a maximum sample rate of 1 GSa/s and a standard record length of 14 Mpts. For ease-of-use, the most commonly used functions can be accessed with its user-friendly front panel design.

The Siglent SDS1104X-E employs a new generation of SPO (Super Phosphor Oscilloscope) technology that provides excellent signal fidelity and performance. The system noise is also lower than similar products in the industry. It comes with a minimum vertical input range of 500 uV/div, an innovative digital trigger system with high sensitivity and low jitter, and a waveform capture rate of 400,000 frames/ sec (sequence mode).

The SDS1104X-E also employs a 256-level intensity grading display function and a color temperature display mode not found in other models in this class. SIGLENT’s latest oscilloscopes offering supports multiple powerful triggering modes including serial bus triggering. Serial decoding is free and includes IIC, SPI, UART, CAN, and LIN. History waveform recording and sequential triggering enable extended waveform recording and analysis. Another powerful addition is the new 1 Mpt FFT math function that gives the SDS1104X-E very high frequency resolution when observing signal spectra. The new design also includes a hardware co-processor that delivers measurements quickly and accurately. The features and performance of SIGLENT’s new SDS1202X-E cannot be matched anywhere else in this price class.

Key Generation[edit]

Python Code[edit]

I used an online Python compiler to spit out the values I needed on my Chromebook.

# Keygen program for Siglent oscilloscopes
import hashlib
# You get this by running "SCOPEID?" at the SCIP prompt and removing the dashes
SCOPEID = '00540d8a5d0a2854'
# Replace this with your SN
# This is one of the four options below
Model = 'SDS1000X-E'
# 'SDS1000X-E', 'SDS2000X-E', 'SDS2000X+', 'SDS5000X', 'ZODIAC-'
bwopt = ('25M', '40M', '50M', '60M', '70M', '100M', '150M', '200M',
         '250M', '300M', '350M', '500M', '750M', '1000M', 'MAX')
otheropt = ('AWG', 'WIFI', 'MSO', 'FLX',
            'CFD', 'I2S', '1553', 'FG', '16LA')
hashkey = '5zao9lyua01pp7hjzm3orcq90mds63z6zi5kv7vmv3ih981vlwn06txnjdtas3u2wa8msx61i12ueh14t7kqwsfskg032nhyuy1d9vv2wm925rd18kih9xhkyilobbgy'
def gen(x):
    h = hashlib.md5((
        hashkey +
        (Model+'\n').ljust(32, '\x00') +
        opt.ljust(5, '\x00') +
        2*(((SCOPEID if opt in bwopt else SN) + '\n').ljust(32, '\x00')) +
    key = ''
    for b in h:
        if (b <= 0x2F or b > 0x39) and (b <= 0x60 or b > 0x7A):
            m = b % 0x24
            b = m + (0x57 if m > 9 else 0x30)
        if b == 0x30:
            b = 0x32
        if b == 0x31:
            b = 0x33
        if b == 0x6c:
            b = 0x6d
        if b == 0x6f:
            b = 0x70
        key += chr(b)
    return key.upper()
for opt in bwopt:
    print('{:5} {}'.format(opt, gen(SCOPEID)))
for opt in otheropt:
    print('{:5} {}'.format(opt, gen(SN)))

Software Codes[edit]

The following codes are generated by the python program. Some of these codes were then used to perform the upgrade. Since the hardware of the SDS1104X-E is the same as the more kitted out SDS1204X-E the scope is able to be un-handicapped to allow the hardware to perform as it would in the more expensive model. The key number to look out for is the one beside the 200M. This will upgrade the scope to the SDS1204X-E's higher 200Mhz bandwidth (in my case MQD6JDIMJH2M9A3Q).The other features that are able to be upgraded are the ability to use the SPL1016 Logic Probe with the MSO code, the ability to use the SAG1021 function generator with the AWG code, and the ability to use a USB-WiFi adapter with the WIFI code.
